Government debt and finances do have a solution and its easy ..... tax the hell out of the rich
It limits the runaway power and excesses of the rich and redistributes some of that wealth back to the people at the bottom. It stabilizes the economy because it distributes wealth and distributed wealth benefits everyone.
Otherwise, if you just build an economic system that only sends and accumulates money with a small group of people .... it works great for a while but it isn't sustainable and will eventually collapse.
But what do I know .... I'm not rich ... it's the rich that benefit from the current system and its the rich that control the whole system ... so I don't see the system changing any time soon.
