I believe that this is quite untrue. Finance is full of clever innovations that are mostly meant to make money for their creators. Because the monetary rewards are so high, it attracts some very talented people.

As just one example, you can securitize the revenues from golf courses. You can say, hey, i own six courses bringing in an average of $100m a year. I'm gonna take that $600m cash flow and sell it in an asset-backed security in order to raise money to finance the acquisition of more golf courses. Then I'm gonna tranche up those securities, because I found that I'll make more money selling 50% super safe and 50% risky than selling it as 100% middle-of-the-road risky. This example isn't really a hack anymore... it's almost the norm. But someone had to have the initial insight and then figure out if this was legal.
