> What stops [someone]..

Interviews scheduled during work hours, already working multiple jobs, burnout, lack of openings in your field

> It hardly is THAT hard to get some competing offers. And if you can't be bothered, I guess you don't really want it anyway?

This sentiment signals bias

Competing offers? For what? Serving coffee? Washing dishes? DBA? CTO?

If you offer anyone with a job more money my guess is 100% would take the extra cash, so just because they fail to find, or look, for more cash how does it imply they 'don't really want it anyway'?
