IMO, the issue is that finance industry is:

(1) flush with cash,

(2) not really understanding tech, or wanting to.

Being flush with cash means that they can tolerate tons of inefficiencies. That's how you end up with low performers and wankers everywhere. Not wanting to understand tech, just focusing on end result, means that the difficulty of tech is underappreciated, best practices are often not followed, developers are treated like cattle instead of valueable contributors etc. There's plenty of issues really. Not to mention that finance it is more ok (than in other fields) to have Trump-style "aggressive" personality, that is in essence anti-intellectual and is super counterproductive for working on complex problems. My advice is to avoid finance (maybe insurance is better, I've never worked there) unless you just want to suffer for a couple years and stuff your mattress with money.
