Here's the rub against Mitt Romney, put simply by Washington Post columnist Ezra Klein:
Romney played by the rules of the rich. “There is an increasing sense in the United States that the rich play by different rules than the poor or the middle class -- rules that make it easier for them to get even richer. Romney's problem is that he seems to have taken unusually aggressive advantage of those different rules. Most Americans don't get to stay on as ‘sole stockholder, chairman of the board, chief executive officer and president’ while they try other things…They don't get to pay a 13.9 percent tax rate because their money comes from investments rather than wages. They don't get to shelter cash overseas, or keep between $21 million and $102 million in an IRA.
When people question these elements of Romney's history, Romney says they're attacking his success. They're not. They're attacking the fact that once people become successful, they get to play by a set of rules, and fall back on a set of advantages, that make it a lot easier for them to remain successful.” Ezra Klein in The Washington Post.
