"It does not help much to take wealth in terms of equity paper money away from people who know how to invest it efficiently and distribute it." This assumes what needs to be proven. Namely, the degree to which the wealth of billionaries under the status quo regulatory, financial, and tax regime reflects their outsized contributions to welfare. If we make a number of assumptions (e.g. perfect information, perfect comp…
>This assumes what needs to be proven. I think it has been, dramatically, over the last 120 years. Plenty of countries have tried radical appropriation and redistribution, and it failed spectacularly every time. Meanwhile a prominent Marxist country, China, turned to capitalism and within a generation has raised hundreds of millions of people out of poverty and into urban middle class lives. Meanwhile Cuba, Venezuela…
How about non-radical redistribution?
In Capital in the Twenty-First Century, Piketty puts forward the idea of a (net) wealth tax on the order of something like:
* 0-10M net worth: 0%
* 10-100M: 0.1%
* 100M-1000M: 1%
* >1000M: 2%
This would allow two things: first the documentation of people's assets (and liabilities) to find their net worth for the tax regime, and second the skimming off the top of a not ridiculous amount of the assets of those that have a lot.
So if you have a $1B portfolio, and manage to grow it 8% in a year, then you end up with "only" 6% growth. This still allows for incentives for people to acquire wealth, but tamps down on some of the compounding that the largest estates end up getting (there's often only so much that can be spend, so a lot of the previous year's gains just end up sitting and accumulating).
The key would be for the US to get onside: by some measures it is one of the largest tax havens out there.

It has global reach which would probably change a lot of international behaviour. Just look at FACTA:
