If it is not a fault to be naive, it can be a big sin to take advantage of naives.

A capitalistic society began as something where some people saved money, lent it to a bank which collecting it from many made a big sum that was borrowed by somebody who invested it and created new jobs which allowed people to have a better lifestyle, spending and saving part of it to build the "capital" and so on...

Today what is left of it is the fact that people who work do not save to make the "capital" but borrow and spend more than what they earn.
The capital doesn't exist anymore, it is something opposite.
A mass of debts, money spent before producing it, a future based on nobody knows what and the certainty that nothing will change unless the society changes.

Whose fault is it?
Of course it is the fault of the ones who knew, who understood, who used the ones who didn't know and didn't understand.
If it is not a fault to be naive, it can be a big sin to take advantage of naives.

"In my narrative, the fate of industrial nations really depends on energy resources".
Of course when you want to produce more and consume more you need more energy.
But to produce a healthy economy you really do not need to increase every year the production to increase the consuming to increase the economy.
Find the right balance and a healthy economy will follow.

May be all this is not for nothing.
May be we will realize on one side that we can live with much less and on the other side that we can have much more for surviving.
The principle of the communicating vases applies to communicating societies.
Peace and economic balance is reached when the water (power, richness,) is in balance.
This is the lesson we have to learn.
