That's the theory and few rational people would argue that those services are necessary. But we've been in a tail-wagging-the-dog situation for a while now. The industry seems to believe that they're entitled to an increasingly large share of the world's wealth. They've seemingly forgotten that they're a facilitator of progress and don't represent progress in and of themselves. They recruit the best and the brightest to create ever-more-complicated financial instruments robbing society of the contributions those engineers/scientists would have made elsewhere. Much like the same cellular mechanisms that sustain life become cancerous when there is unchecked growth, the same financial apparatus that we need to facilitate progress becomes cancerous when its growth is unchecked and it loses focus of the purpose that it serves.
