To piggy back on this, as a thought experiment, if you took all the wealth of every American billionaire combined you would pay for the US government for about a year.
Top 10% wealth is $113T. Government is operating off of $5T revenue.
Seizing all of it and putting it into even a foreign owned asset basket (could pick an economy as shielded as possible from US in case it causes instability in US economy) should yield enough interest (at least 5% real) to operate the federal government and public entitlements indefinitely based on present real revenues.
It's not clear if this is meant to be a serious thought experiment, but nonetheless I would ask why you equate expenses ($6.8T) with revenue ($4.9T)? I suppose it might not make a big difference, but it's a strange decision (within an already very weird thought experiment.) Also not sure why you picked top 10% wealth, since the previous comment was about billionaires. The top 10% of net worth starts with low millionaires so... goodbye every single employer, I assume.
