At the same time, don't let a company string you along
I think your statement isn't strong enough. Choosing lower compensation in exchange for work that aligns with your value system is an entirely rational thing to do.
I'm not saying there's anything wrong with that. But, in my experience, that's not representative of most people.
A) rarely have a clear view of their values insofar as it aligns to what they do for a career or job. Maybe about X social issue, but rarely about themselves.
B) careers and corporate brainwashing greatly distorts peoples internal view of themselves and their relationship to their work
C) values change continuously throughout life. The people who seem to hold most tightly to a narrow range over a long time tend to be the least introspected.
