There's lots of assumptions in your comment. I address some below but you ARE starting to understand the potential of this system.
I'm in full agreement that this shouldn't be done on a socialist basis. I laid all of it out numerous times for how to do it with nothing more than taking back the fruits of our labor. In fact, this is the inevitable society of a completely free market society!
IF (key word) we stop paying banks every dime, they would go away.
If so, we would literally have 4-5 times the income for our current efforts. If so, we would stop buying disposable crap and start buying long lasting quality items. That further saves us money.
If we stop paying monthly for services that we could own (think solar power as one example), we would quickly pay it off and save much more.
If we had enough money saved up as a result of the above, we would never buy insurance. That saves a ton more.
If we accumulated all of the above, we would never let our kids, family or close friends take out a loan and pay interest. That saves the rest.
If we did all of the above, we could earn a better living by one parent retiring at age 30 than two parents can do today. If that was possible, many people WOULD retire then. That would reverse the unemployment problem. Making it a worker shortage would put the power back in the hands of the workers and 'fluff' jobs would be replaced with automation (if they were needed at all).
As the tech advances, it would become easier (already has) for the average person to run small, local businesses that directly compete with large, global corporations. This puts local accountability back into the hands of the local community. This solves many other social problems.
The end result of simply making our beloved free market work the way it was meant to: We would have 5-15% of the current employment force providing more prosperity than most people can imagine today. They would then retire after their 20's (or maybe only work the decade of their thirties), knowing that if their retirement ran short because they didn't plan it well, they could return to work for 6 months to earn another 5-10 years worth of savings.
The reason is that savings now comes from discretionary spending which is a small part of our income. In this system, savings would rack up equivalent to the full pay.
Is this utopia? Who cares? Getting into that discussion is pointless because people ASSUME there's some negative connotation to it. There shouldn't be. By definition, utopia is without problems for all. Unfortunately, people assume it has to come from the government and I'm saying that it can essentially make government a completely moot point.
