The existing system could, however, be improved. There is a way we could eliminate unemployment and poverty as well as taxes/public debt while increasing sustainability, with built-in protections against inflation.

This idea is obviously revolutionary, but it is not radical: no existing institutions would be torn down and the economy would continue to function as it does at present--except that it would be completely self-regulating (so, no 'managing' it by government or the central bank).

All of that would be accomplished with a single legislative Act, without imposing any cost on employers, without redistributing anything, without imposing any limit on income/wealth, without additional regulations, and without requiring people to act any particular way.

It could be implemented by any nation. It can be thought of as a kind of "Permanent 'Quantitative Easing'" (here in Medium, but not behind the paywall).

The closest this paradigm comes to having a 'catch' is that money would have to be returned to its creator (probably the central bank), but people and businesses would be able to retain plenty of money, based on income, and no money would be collected from any person or business before it could be used for purchases/investment. Any individual would have to be totally asleep at the financial switch to have any money collected.
