Of course Jeff isn't in the position to sell his entire Amazon shares, so the $150K is more symbolic than anything.
However, a 3%-6% wealth tax (or even a basic VAT) would help redistribute wealth and fund healthcare, infrastructure upgrades, energy security. 3% is fairly modest, but definitely do-able when you're Jeff Bezos.
We normally try to tax income or consumption for a reason, because taxing capital is incredibly damaging.
And we could seize all of Bezos net worth, and it would only cover a few weeks of federal spending. Of course we could push it closer to 2 months including Bill Gates, Elon Musk, and Warren Buffett, but what do we do when we run out of billionaires in a couple years?
