That seems naive? All sorts of industries have nice side/nasty side, and it's often very dependent on both which company and which job title and even which individual manager you get. This is why Glassdoor is a thing.

At the end of the day it's all anecdote, but the plural of anecdote can be opinion even if it's not data.

The cost center heuristic is good: is the work you're doing an important part of a product being sold? If not, you're just a cost like office cleaning, and will be treated and paid accordingly.

Apart from banking (process-driven, often boring, can be well paid) the other big stereotypes are consultancy ("body shop": cheap and nasty; higher end consultancy can be hugely lucrative but very political) and games (almost uniformly appalling, only work for a games company if you really want to be able to tell your friends you do so)
