Currently even stable currencies inflate. That means that the energy you put into making that 20 bucks is slowly and steadily being sucked out. The only way to prevent that is to give your money back to the bank (invest). Pretty neat trick they played on all of us. Take the land. Indebted for life. And now, everything we make will be worth nothing, eventually, unless we give it back to them to play with. We are just pawns, the majority, and most people know that instinctively; which is really my point. It's time we stopped listening to capitalist dogma and come up with a plan that suits all of us, soon.
We could have an economy that looks pretty much the same as it does now. People could start and run small businesses and employ themselves as the the chief at whatever would be a reasonable salary for that position. Same for their employees, market rate. A CEO could make say, $300,000 a year for running a large company. It's a lot of responsibility, really. The only real difference would be the complete erasure of any job involving the shuffling of funds, owning of land or skimming profits. In basic terms, if you aren't doing anything, you get no extra money. Jobs are where money comes from. Holding hoards of money or land and lending it to people is not a job, it's a racket; perhaps a necessary evil at times, but if so, let the public profit, not the fraction of one percent that learned exploitation and control centuries ago.
You have to lop the top off the economy, and let everything below the finance level function as normal. People doing things and getting paid. All financial concerns would be public and transparent, overseen not by a small group, but by hundreds of rotating public auditors constantly checking for corruption.
Remember that in my "magic world" all necessities (which were here on the earth before they were privatized, lest i remind you) are granted for free, so wages would be only for extra things that you wanted, like cell phones, computers, etc.
You wouldn't need to work. Money would be less important, but not unattainable. You could still have the same life you have today, but without the worry and fear that is induced by our current system. Public mental health is an important component of a healthy society that seems to be overlooked. In fact, that state of fear and anxiety is promoted and exploited to keep us all compliant. My advice to anyone would be to shake it off, use some courage and stand up to the minority that pours billions into maintaining our common neurosis. We have not lived yet.
