Money is a factor, but not the only one, and for some, not the most important one. Beyond a certain point, there are diminishing returns. Does driving a car that costs twice as much make you twice as happy? Maybe for the first month, then it's just normal again.

For me personally, quality of life is important, so is vibing with my coworkers, and management that respects work-life balance. I have this at my current job. My salary is good, not amazing but comfortable. Would I trade double the salary for an environment where I'm stressed, expected to work 50 hour weeks, and answer calls on my own time? Nah. No way.
