I believe I read 8 out of the top ten income zip codes voted for Obama in 2012. Most of the super rich have gone over to the Dems - the trust fund babies, the hollywood elite, the Harvard educated financiers.
They support higher income taxes because they’ve already amassed their wealth and won’t feel a few extra percent taken from income. Let’s give them an federal property tax they can feel. For all billionaires, let the federal government take 4% of net worth per year. Warren Buffet has an estimated net worth of $46 billion. At 4% he will pay $1.84 billion, some serious money. Soros, Bill Gates, Jeffrey Immelt, Oprah, Tom Hanks, and the other super rich demanding higher marginal tax rates their tax shelters will let them avoid might change their tune with a real wealth tax - a tax on accumulated wealth for billionaires. If the Dems hate wealth so much they should be happy to sign on to this.
