Have you done the math, though? Consider the not so extreme nonhypothetical of how many Zuks it would take to make Medicare/Social Security solvent.
The only way to make an amount of extra taxmonies actually worth getting up for is to tax the middle class. Alas, economics is not a zero-sum game, some people have invest their wealth to actually produce stuff to make it all work, and this mostly comes from the wealth of the middle class.
I haven't but others have (e.g. Warren). A 2% wealth tax on assets over $50M will generate $3.75T over 10 years. Even if the actual number is half of that, it's still plenty to pay for many progressive programs.
The total number of billionaires in the US will drop to zero a week before this is passed into law (or maybe one or two, the remaining being people who have decided that ultra-virtue-signalling-slash-conspicuous-consumption is worth 6%/yr and who have nevertheless squirreled away most of their wealth into various nonprofits and the like), and the number of people with assets over $100m will dropped to maybe 5%. Unless they plan to retroactively tax people fleeing before the law passes, I doubt it will generate one-twentieth that amount. A person with asset of $100m will be paying $1m/year under that system. Uprooting yourself from the US is painful, but $1m/year soothes a whole lot of pain. Even more so for billionaires.
If it does become law, though, I fully expect that $50m ceiling to come down year by year as the economic situation worsens until sub-$1m. Or maybe they keep it the same and hyperinflation will meet it on the way up for the same net result.
