You're right, it's just too hard. We'll leave it to the billionaires to solve - I know one who says he's the only one who can fix it.

Sorry, my cynicism is showing. But we already have the organisation (IRS) in place to regulate people's income, and they already do exactly this job. Yes, we do need to find an impartial way to redistribute the wealth, but we have working models of an array of options around the world. With functioning government, this is really not that difficult.

This hints at the ideological chicken and egg problem here - wealth centralization breeds power centralization which breeds state corruption. The corruption of power through centralized wealth is presented as defenders of such wealth as an indicator of the states inability to impartially control such corruption.

The trick is the corruption already happened. The money was already too centralized, and has already done damage to the integrity of public institutions. That however is not a reason to abandon such institutions in favor of the monied interests that brought about the corruption, it is a reason to more seriously pursue means to purge the corruption and restore democracy. When that centralization of wealth causes that corruption, that means you need to address that vector in your ideology and policy goals as a citizen.

Ignoring it is just a long term means to eventually collapse the society as a self sustaining growth of both inequality and corruption consumes all prosperity and growth.

Reducing power centralization is the key issue. Lobbying is cost-effective, and it shouldn't be.

> who gets/takes the money?

The default option is putting it in the government budget. Seems obvious to me.

If we reach the point where this cap-tax is able to pay for the entire government by itself, and we still have extra, then we can worry about where the rest goes.

> Who enforces/regulates that people are only earning/saving what they are allowed?

The IRS.

We don't have a tax on wealth in the US at the moment. Implement a tax on wealth with a 100% take over say 1 million? This would just be basically the nationalization of most of the companies and much of the real estate in the US. We could try communism/socialism at this scale, but it has not worked out well in other places it was tried.

That's the "ugly" part. And it gets really ugly.

Yeah, nationalizing all companies would be ugly.

And has nothing to do with taxing personal wealth over 10 million (or other arbitrary big number).

It doesn't get ugly fast. The tax rate for the wealthy used to be 90%. There was a time in the country where it was recognized that robber barons were not in our collective interest. This is not an unsolvable problem.

90% tax on income not wealth. Our current system already punishes income earning over wealth growth and much gaming goes on by the rich to keep wealth growing while keeping taxable income low.

Generally when talking about tax rates in this context it's about the income tax. There is no wealth tax in the U.S. I don't think there ever has been one either. Reagan believed the tax on labor should be less than the tax on capital. I agree with him on this but the current Republican party has deviated quite far from where even Reagan stood.
