That is a great question -- but there are also other aspects to the problem -- human talent is one. Finance can extract rents from society, and it can also lure away promising PhDs, academics and many of the brightest with superior salaries (financed via rents extracted.) I'm not passing judgement on the workers here -- I was one, trapped in the system for 10+yrs with golden handcuffs and nothing to show my family on what I actually created.
