Josh Marshall nails what I think the problem is most people have with Mitt Romney. Romney suggests they resent him his great wealth. No. They resent him his low tax rate.
I would also suggest that there's a difference in this country in how we regard wealthy folks who got rich by making an actual product and those whose wealth has chiefly come from the manipulation of money and investments. If Romney had invented the George Foreman Grill and made his millions that way, I don't think anyone would begrudge anything about his fortune. But no one can name anything that Romney as a private individual gave the world. He just knew when to buy and sell…and maybe even when to strip-mine a company and kill it.
