Your sentiment that the truly rich make their money outside of a typical paycheck is correct though. It’s a balancing act of how do we tax people who have accumulated so much wealth in capital vs taxing capital so much that people don’t invest in it.
I don’t pretend to have the answer there but spreading disinformation that professional working people would be hurt by a 70% rate on every $1 over $10 million is pretty irresponsible.
