When the nerds with their voodoo were making lots of money, the firms didn't say "we don't know what these guys are doing, but they are making us lots of money, they deserve all the credit, they are the heroes", instead the CEOs gave each other big bonuses and pats on the back. But when everything went sour, they blamed the "nerds" (and I admit, nerds did screw up), instead of blaming themselves for not evaluating risk properly. If they couldn't evaluate risk properly (and I think they couldn't), they should have stopped what they were doing.<p>EDIT: syntax errors
