I've been screaming for decades now, that we need wealth caps. Why the fuck is it okay and acceptable that a single person can get full % of the entire world's wealth? Or whyneven do we allow billionaires? Or centillionaires. Nobody should be able to have a networth of over, say, 5 million dollars. You reach that limit, all your additional income goes to taxes, 100%. And, of course, if you're at, say, 4 million, the income tax should already be around 90% or so to avoid shenanigans with a rolling income / expenses scheme

When we no longer have billionaires, the game changes significantly. No longer will one single narcissist be able to accumulate power. Resources will have to be spread over the population as no single person can own a large company.

This will also limit the size of any company. A single person can have a million dollar home, a million in other things like cars, etc, and thenaybe have 2-3 millions tops to invest in companies. This means that a billion dollar company will need at least 500 relatively rich people to be share holders, and in reality it likely will be more like 5000... This will limit the size of companies, this will make smaller companies that are more focused on fewer products.

Putting this single limit in place, world wide, will change the world in an extreme way

It will also never happen until politicians will actually start listening to citizens and citizens will be educated enough to understand what they're voting for, and politicians be required to not lie... So yeah, good luck.
