I'm supporting a family on a semi-remote job (work from anywhere, employer covers my airfare to our offices as needed), and when I unexpectedly parted ways with my previous employer last year, I doubled my compensation in 2 weeks. "F* you, pay me" is a legitimate operating philosophy as an employee when your skills are in demand. Also important to live below your means and have a 1+ year runway of savings to enable you to negotiate from a position of power, but that's a conversation for another thread.

Better said above, "Working for “passion” is for suckers."
