For example: lawyers often make a lot of money. But they work 12 hour days during the week, and often a lot on weekends and holidays. I would hate that. No amount of money is worth that much of my time.
Would you want to work for a company that pays a lot if you don't agree with their mission? If they do something you find morally objectionable, would you work for them anyway just because they throw cash at you?
Quality of life, work-life balance, stress, hours...all these things come into play when choosing what career and what jobs you choose.
