> It would be nice if society was set up such that there were more "work hard" paths to financial security as opposed to risky paths, but we collectively can't shake this risk-reward caveman mentality, so people go into law or finance.

This is precisely my point. If we set things up so that finance and MBAs weren't the things that lead to financial security then things would be much more efficient. Because people would be rewarded for the things that are creating value, rather than having to make choice between creating value and earning more money.
