Musk’s wealth is almost 100% invested in his companies. He’s only mega-rich on paper, and he doesn’t care. Last year, he paid $11B in taxes. Not enough for Bernie. What Bernie really wants is to take his companies away from him.
Unrealized capital gains, which Bernie wants to tax now. That $11B was from sales of stock (realized capital gains).
Bernie and the Democrats would love to tax us now on our unrealized capital gains (401K's, invested retirement plans, etc.).
