The contrast between George Romney and his son Mitt — a contrast both in their business careers and in their willingness to come clean about their financial affairs — dramatically illustrates how America has changed…

First, however, let’s talk about what it meant to get rich in George Romney’s America, and how it compares with the situation today.

What did George Romney do for a living? The answer was straightforward: he ran an auto company, American Motors. And he ran it very well indeed: at a time when the Big Three were still fixated on big cars and ignoring the rising tide of imports, Romney shifted to a highly successful focus on compacts that restored the company’s fortunes, not to mention that it saved the jobs of many American workers…

Now fast-forward to Romney the Younger, who made even more money during his business career at Bain Capital. Unlike his father, however, Mr. Romney didn’t get rich by producing things people wanted to buy; he made his fortune through financial engineering that seems in many cases to have left workers worse off, and in some cases driven companies into bankruptcy.
