If you look at economic research in Europe, you'll see many other opinions, like about the importance of the state, or alternative economic models. You'll probably find studies against HFT also.

Another comment that comes to mind is from Warren Buffett, who famously called derivatives "weapons of financial mass destruction" years before the recent blow up.

Buffet never described derivatives as creating a housing bubble. Buffet's problem with derivatives is that they make accounting tricky and fraud easier. But have no fear! Moodys (which Buffet owns about 20% of) will distill the complex accounting down to a simple letter rating. If Moodys calls a derivative "AAA", you know it's safe.

Snark aside, this was not a prediction of a housing bubble. CDO's did exactly what everyone thought they would do. They behaved like AAA securities for as long as the beliefs underlying them held true ("housing never goes down").
