Finance has been a glorious, high paid profession for much longer than tech. Tech only became glorious in the mid-late 1990’s and has proven to be a continuation of the corporate raider mentality of eviscerating companies into top-heavy laden enterprises. Basically, “productivity” increases is the manifestation or facade if you will of these ideals.
You may think that it doesn’t matter what the vast population wanted, but the slack in the system has been narrowed so far now that even the last bastion of the Fed cannot bail out the top-heavy institutions much longer.
