I worked in financial trading for a few years in the 1990s. It was the same deal then: pay was great, industry was a boys club run by assholes, work environment was toxic. After a few years I was very much burnt out and had to change careers from sysadmin work to software development as my internal reaction to being asked to do sysadmin had become waves of nausea and hostility. Took me years to get over it.

So if you are tempted to do financial industry work, make sure to price in the risk of lost work time, years of therapy, etc. It was a fascinating experience and I learned a ton, but financially it was not a net win for me in the long term.
