The rich don't do it. The private sector mostly employs two types of people: low wage, often temporary workers and ultra high wage executive types. About the only people who actually have a middle class lifestyle are government employees, university employees, professional political activists (think tanks), etc.
Further, you idiots, the rich have already gone. Capital is mobile, and capital left the US a long time ago. They aren't investing in the United States (other than in buying more control of the government), they are investing overseas.
Do you honestly believe that only the people who are currently rich (who mostly got rich by rent-seeking and other forms of scam) are capable of creating jobs and running things?
"The rich" (the actual rich, the wealthy, not the 250k middle class wage slaves) are overwhelmingly pie in the sky progressives. We'll be FINE without them.
