I have this loose theory that those in government want to use taxpayer dollars to have 'cool jobs'. The people who build plans for sports arenas (which almost never pay off) would actually rather own a sports team. The people who want government to fund social services would actually rather be doing charitable work but they don't want to have to worry about how the money is spent.
By those accounts then, Obama and his staff would like to be bankers and investment managers, but they don't want to have to worry about having to turn a profit. They have funneled huge dollars into investments that will never pay off in any fiduciary way, but have yielded HUGE benefits in the form of campaign contributions and union strength (which is the same as campaign contributions except further out on the forward curve).
Obama's never run a lemonade stand, and doesn't look like he'd be any good at it if he tried. But since he's trying with our money, at least he doesn't have to worry about his friends all going broke. He'll never have to pay the bill, we will.
