World wide wealth caps, implemented though taxes
Have tax brackets as we know them, but more brackets with one final bracket: As soon as you reach, say, 10 million dollars in net worth, taxes on income and anything that increases your wealth go to 100%. Anything over it also gets taxes 100%
This way nobody gets to be filthy rich.
Governments get huge influxes of funds that they then use for a large socialist system. Universal free healthcare, free education for anyone that wants it. Free housing where needed, universal basic income, you name it
Governments can fund independent news foundations that in their turn fund news organizations with the most important rule that news always must be as factual and unbiased as possible
Since nobody can be filthy rich, or dirt poor, its hard to bribe people because people are fine with the money they have
Worried about people hiding wealth? Make all financial data public. All of it. If nobody can go over 10 mil anyways, who cares that it's public
Since nobody can be filthy rich, nobody can be filthy powerful, which is good as power is the root of all evil for humans. Want to wage a war? Good luck with that without power to push for that
Since nobody will be dirt poor, most crime will disappear. Scams will disappear because incentives for those things will be gone
Most people would never hit the line, and they'd be fine. The few workaholics under us will be able to get "rich" and hit that line:
10 mil gets you a very nice house and car and some investment money for a company maybe
Want a bigger company? Get more investors. This practically goes to the point where companies are owned by the employees
Governments can also fund independent investment foundations where needed for bigger companies but I'd keep companies limited in size too, let's say 1 billion dollars in net worth max.
This way, no powerful companies that will fuck over customers. No powerful companies to lobby governments to fuck over the people. You will no longer have these too big to fail companies either. Better 5000 1 million companies than one 5 billion dollars company
We can even keep capitalism as we currently have it because capitalism is basically free trade. Trade all the crap you want, its fine, as we now have simple basic limits to the system. No need for changing systems ehatbeill guaranteed cause shitstorms
Yes, the 10 mil is rather arbitrary, and should be subject to inflation and so on, but you get the basic point. I'm sure an economist could come up with better limits, and I'm sure we'll need to add some details here and there, bit the basics is simple.
The hardest part of this is that you'll probably need to implement this world wide all at the same time, and you'll probably want to have all countries using the same currency (which would also simplify the crap out of so many things)
