Resource allocation in a modern economy is a complicated technical problem. That's the problem investment banking was invented to solve. That it has been corrupted doesn't alter this basic idea.
I could be totally wrong here, but I get the sense that despite that being the intent of wall street, that basic concept has been very much abstracted away into a complicated game of mutual insurance and risk management.
All I'm saying is that perhaps society would be better off if the resources were allocated a little less efficiently, but those "best minds" were applied to some other field.
