social problems are generally created by the for profit economy.
At this point in the economy, I think the biggest problem is scarcity. Who needs endless stacks of money if we are all able to receive the same from the supply. But some people get caviar while other get sardines. Money isn't just the energy but it is also the barrier for things that are scarce and in demand since there are too many people in this world for everyone to enjoy the caviar.
Of course the money supply could be spread out more evenly. But now physical might has been swapped out for financial might, so those without capital are forced to go without due to scarcity.
