It probably doesn't help right now, but you should know you are not the only one in your situation. Perhaps it might help to write down your actual principles. Then compare that list with the real reasons you refuse some employment opportunities.
I think you have already listed one big reason that isn't a high-minded principle. You want to make money. There may be others.
It's always wonderful when you can make a lot of money doing things you love to do. It stinks when you have to choose between what you are exceptionally good at doing and what your principles allow.
If only somebody could figure out how the talents of all the people in your situation could be used to restore housing affordability. Would you take a 70% paycut and move to Nebraska if it allowed you to keep all your other principles?
As you say, kindness isn't hiring. I'd love to see an HN discussion of all the good causes that need founders. It would be wonderful to have some well known efforts where the underemployed could devote some energy while they licked their wounds. It might even be useful to have "Goodworks Volunteer" fill that gap in employment history on your resume.
How do we get a monthly "What good causes need volunteers?" post on HN?
