This is an article about carried interest, which is a certain partner — usually a working partner — to get a disproportionately large share of the profit from a venture. It is not unusual and has been around since at least the 70s. If the venture throws off capital gain income, the carry partners get capital gain like anyone else. This was never controversial when Romney did it. There was a move to tax carry like ordinary income in the Dem controlled Congress but they didn’t do it because their supporters vetoed it. Obama didn’t push it because he gets Wall Street money too. You can argue that it should be ordinary income but until it is, there is nothing wrong with taking it as compensation. Especially since it is putting your compensation at risk (imagine not getting paid unless you were successful at a project). This is a bogus line of attack on Romney.
Attack?
Everyone is just getting a good look at the entire picture.
