As always, why is the magic number a billion dollars? And how do you draw the line in regards to stock ownership, prevent a founder from owning a certain amount of stock once its value exceeds a billion dollars?
As always, pick one and deal with it. This whole "billionaires are geniuses and figure out the world's hardest problems but simultaneously can't figure out how to be taxed" shtick has run its course. Of course, no solution will be perfect. That's life and how everyone else deals with things.
There are several ways to accomplish taxing the mega-rich that don't require rewriting the laws of the universe. It's just that nobody in charge, because they're either the mega-rich themselves or puppets of the mega-rich, wants to address it.
Middle-class folks are taxed at 20-35%, so it literally works all the time for everyone else. Inequality continues to rise and wealth continues to concentrate. This is because taxes that used to work and be in place for the rich are no longer there. The wealthy used to pay much more tax.
Are you seriously okay with the ultra rich living by completely different rules than everyone else? I think it's probably underestimated how much they get away with not paying.
