Potential simplicity is the ability to store up the ability to
simplify one's life (reduce consumption), in advance of needing
to.  Trustworthiness is proposed as a source of potential simplicity.
Trustworthiness is Potential Simplicity
Degrowth: intentionally shrinking the economy. Overall, everyone 
consumes less and works less.There are different reasons why we might
want to make this happen.  We can live simpler lives.  We can have 
more time to think, walk, socialize, sleep, pray, listen to music, stare at the 
wall, meditate -- anything time-consuming but not resource-intensive.  
Also, we can impose less of a burden on Earth: less soil depletion, 
species extinction, fewer greenhouse gas emissions, and so on -- all 
of which affect how much we and our descendants have to suffer, and 
how likely we can survive as a civilization -- maybe even as a species.
How can we consume less as a society?  To an extent, we can blame 
the rich.  They do consume more than poorer people.  But both rich and
poor have to consume less.  And we all have to consume less of the 
things that make our personal lives function.  Everyone needs to 
eat, most everyone needs some kind of shelter sometimes, most everyone
needs to get around, and there are a few other basic needs.  We have
to shift our basic needs from expensive versions of them, to inexpensive
ones.  The poor in the United States, for instance, make less than 
$12,480 a year (the official poverty line).  $12,480 is a huge amount 
of money compared to what the poorest in some other countries make (closer 
to $500 a year).  Poverty is expensive in the US.
So everyone in the US, on average, has to consume less, pay out of their food, 
housing, transportation.  Somehow this is possible -- people in other
parts of the world already do it.
It's possible to crash the economy by the average person consuming 
too little, too suddenly.  So rather than suggest that everyone simplify 
their lives (no more restaurants, suburban houses, or minivans; everyone 
switch to peanut butter and white bread, SROs, and bus-riding), I think 
it safer for now to encourage everyone (as many as possible), to 
increase their potential to simplify.
How would this work?  One way is to explore simpler lifestyles so 
that they seem less psychologically daunting.  Take it one element at a 
time, and go back to full consumption whenever you want to try a 
different element.  If society is comfortable with simplification, we 
will have more political will available if there's ever a time we can 
simplify all together, at once, in an economically safe way.
(If you really like a simpler lifestyle, you can spend what you save 
from simplicity on charities, such as those that alleviate poverty in 
developing countries.  I am not an economist, but I think in our 
global economy, if the charity spends the money, or gives away the 
money, in some part of the world, global spending will remain the same 
as if you spend at home, and the global economy will have as much cash 
flowing through it as it's already balanced to function with.)
Another approach is to amass any kind of non-economic wealth that can 
help out economically.  One example is given here, which I will call 
"potential simplicity".  An object in motion can run into things and 
cause a scene, and can have a lot of kinetic energy.  An object at rest, 
doing nothing visible may, depending on its position, can have a lot of 
potential energy.  The economy is a somewhat delicate system that can't 
handle too many wild or sudden energies.  But potential economic energy, 
in the form of potential simplicity, for instance, shouldn't be a 
problem, and can be built up with gusto.  Here's an example of potential 
simplicity related to housing:
When you pay $800 for a room in a house, what are you paying for?  
Some of that money goes to maintain the house itself.  But a lot of it 
goes to some property owner, and they spend it on food, housing, cars,
etc, and who knows what else.  Well, what are they doing for you, 
the renter?  You can maintain the house itself without paying them.
Who builds houses in the first place?  People with money.  So they 
would only do this act if they thought they could get their money back 
through rent.  So built into the housing market is the cost of building 
new houses.  If an area is easy to build in, housing prices are lower.  
If people want to live somewhere badly enough, developers will find some 
expensive way to accommodate that desire.  
In my neighborhood, there are some apartment buildings, and some tract 
houses, built long ago when the area was the edge of town.  Because rent 
in San Diego is going up (or perhaps partly for other reasons), gradually 
these tract houses are being converted to rental properties.
The rental properties (I would guess) use each of their available 
bedrooms, or close to that level of occupancy.  But the tract houses can 
easily have fewer than one person per bedroom.  San Diego has high rent 
due to lack of supply relative to demand, but could accommodate its 
current demand at a lower price, and build fewer new units (use less
energy, fewer material resources) if tract house occupants used all of 
their rooms.
Why would anyone buy a house and not use all its bedrooms?  Sometimes 
people use bedrooms for purposes other than living quarters.  A home 
office or gym, for instance.  Can these uses be converted to housing 
people?  If the value of a room is $800 a month (about what it can be in 
my city), then it might be worth finding a way to make alternative uses 
of the space.  Being a regular at a coffeeshop ($150 a month) (or just 
working in a different part of your own home) could replace a home 
office, and a gym membership could be less than $100 a month.
Another reason is that people bought a house when their children were 
young, and the children have "left the nest" and now they don't want to 
move.  In this case, they do not rent for different reasons, some of 
them being that they haven't thought of it, and also, importantly, that 
people aren't always trustworthy and wouldn't make good tenants.  It's 
not worth saving some money if you go crazy or get taken advantage of.
"Trustworthiness" can be reckoned different ways.  (Consider the hierarchy of betrayal).  If you have to 
live with someone day in and day out for years, you might not be able to 
bear issues that you could pass over for a week or two.
As people age, they tend to get isolated.  So what if, as you are in 
your twenties, thirties, and forties, you invest in relationships with 
people with whom you could share your house when you are in your 
retirement years?  This would be a way to store up potential 
simplicity.
So far I've only talked about the gains that could come from using 
all bedrooms as single bedrooms, rather than for other uses.  But some 
people share bedrooms, usually cohabiting couples or spouses, or 
siblings, but in principle, any two sufficiently compatible people could 
share a room.  The potential gains in space from this cultural 
innovation (or re-discovery) would enable San Diego to house something 
less than twice as many people without building any new units.  Judging from 
my bedroom, two people like me (I don't have too much stuff) could share 
a ~11x13-foot space with a certain amount of inconvenience / adjustment.  
One adjustment would be to coordinate sleep schedules and times to have 
the room to oneself.  This would be workable, if the other person were 
trustworthy.
There are two angles to this problem of finding trustworthy people: 
finding people who work for you, and making yourself someone who works 
for more other people.  There are parallels with dating.  Fortunately, 
the two pursuits overlap a lot, so that energy spent in one area has a 
return in the other.  One would pursue friendships, learning what 
kind of people work and what kind don't, turning away from the aspects
in you that do not respect other
people, learning to forgive, accepting back people who can be trusted 
and moving on from people who can't, learning to not be addicted to 
people but instead being in some sense emotionally independent.
Some attention needs to be paid to the art of living with other 
people, and developing attitudes of the heart specifically optimal for 
living with other people, overcoming bad habits that don't come up when 
you have more space.   Not as much as in a marriage, because these 
rooming or housing partnerships don't have to be as long-term or as 
personally involved, but comparable.
A group house of four or eight people has different dynamics than a 
studio apartment shared by two people.  So it is good for some people to 
learn how to spend time together and manage common resources as a 
group.
In order to pursue friendships, one would seek groups of people from 
which to find friends.  One might also develop the life path of being quiet 
and not needing as much human connection, to share a house or a room 
with someone like that.  Trustworthiness varies -- as far as humans are 
concerned, only consists of not betraying some other person and society 
at large.
Trustworthiness is both a trueness of heart, inner strength, and a 
learned skill.  People call some people "real, deep, legit" -- such is 
good material for trustworthiness.
Interpersonal trustworthiness, directed toward shared housing, can be 
an economic and environmental asset.  Fortunately, it's a value shared 
both by the left and the right.  Also, it's a value that pays dividends 
to individuals even if society as a whole does not commit to the norm of 
shared housing.  It can be extended piecemeal.  The poverty of the 
materially rich is isolation and broken relationships, and the poverty 
of the materially poor can include these as well -- a message that can
be profitably heard by people from all different socioeconomic groupings.  
As it is a potential for economic change and not a direct economic 
change, it may be able to pass under the radar of the forces that try 
to constrain individual spiritual lives to patterns which preserve the 
economic or political status quo (which is both oppressive and fragile 
and could fall apart).
I have focused on housing so far, but how does this affect 
transportation?  Probably the "cleanest" solution to transportation 
problems is to find ways to locate people closer to their jobs or 
anything else they travel to regularly.  People who know and trust 
more people have more choices of where to live with other 
people, allowing them to move closer to work.  It would probably 
make sense to create "company town" type scenarios (cluster 
complementary workplaces in neighborhoods where their workers and 
support personnel live).  This involves a certain amount of 
uprooting and rerooting of people, which is easier if people have 
strong relational ties with those they live with, overall emotional 
bases, and a greater ability to get along with strangers, and 
improved by working on trustworthiness.
What about food?  The spread of vegetarianism and veganism is a 
low-hanging fruit, but we may still need to eat less per person.  
How can we deal with constant hunger?  To some extent, we can 
adjust to it, get to where we don't need as many calories.  But to 
a certain extent, it will never comfortable.  How can we get 
through mass discomfort?  The skills of patience (endurance and 
waiting) are improved by trustworthiness toward others, as well 
as having a good relationship with yourself.  When you relate 
well to yourself, you can tell yourself "no" and believe yourself 
when you promise yourself that things will be better in the 
future, when you will get what you desire.  (Much of what we seek 
from other people in relationships, and what we get from the process 
of increasing trustworthiness overall, is really about our 
relationships with ourselves.)
There are other basic needs, which should be considered in more 
detail elsewhere.  In general, it is easier to consume less of a 
resource if you have some compensating factor, a rich relationship, 
a lack of abusiveness in your life.
When a certain number of people are ready to simplify, a regulatory
body (probably a government) can put out advertisements encouraging
people to cut back on their consumption, for instance by moving into
their friends' houses to free up housing.  We will all know what's going
on and be able to plan for the decrease in housing construction as a 
society, or whatever other consequence comes from simplification.
This article has been mostly written with those on the left in mind, 
more secular people, or religious believers with some degree of sympathy 
with secular culture, or at least those accustomed to it.  But the 
basics of this article are valid and obligatory for those on the 
Christian right as well.  (My sympathies lie with them as well as with 
those on the left.)  How so?
Perhaps what follows will seem like something out of left field to 
secular readers, but it's important to remember that the world 
we all share is large and contains many different points of view.
Sin is that which God finds unacceptable.  God does not like it when
we do not respect him, or other people.  Much of what is considered 
sin falls under that category of disrespect.  God does not want us 
to sin.  So if we are in tune with God, we will sin less.  Are we ready
to be in the Kingdom?  Or are we holding on to sin?  I like the motto of this site: "Overcome Sin, for the Kingdom
of Jesus Christ is Coming Soon".  Maybe the end will come through
climate change, or maybe not.  People have thought the world was
ending before and been wrong.  Maybe the world is ending in a year.
There's a lot we don't know, but the Kingdom is coming soon, and so,
overcome sin.
It's the Christian's task to build up the Church, which often
means, building up a particular local congregation.  "They will know
that we are Christians by our love" -- "Let love be genuine" -- so 
relationships within churches need to be strong and not abusive, 
characterized by respect.  This is a good in itself, but can also
connect to surviving on Earth in difficult times.  Even if climate
change is a left-wing hoax, building up trustworthiness is a good
idea.
Simplicity is a Christian value.  You can't serve both God and 
Mammon (possessions).  You can have possessions without serving them
in your heart, but if have more than you need and are unwilling to
give them up to honor God, then you are serving them.  Forget about
degrowth.  That's a secular agenda.  Be simple for Christian reasons.
So, many different kinds of people can see the use of simplicity and
trustworthiness which feeds into it.  Therefore, potential 
simplicity (and then simplicity itself) could actually be adopted as 
a mass value and put into practice.  In 50 years, or 20, (or sooner?), 
policymakers could use this resource to lower rents and cut 
greenhouse gas emissions.  And Christians could be closer to God.  
And for more pessimistic minds, trustworthiness and relational 
wealth, and the ability to live with less, are a good thing for 
everyone to develop, in the event of societal collapse.
