That’s never how it’s been described to me. That’s always been known to me as FI/RE or just being rich. FUM is simply the ability to walk away from a job and be very picky about where you work.
I do like that mindset as that definition of FUM is much easier to achieve than FIRE. However, I always assumed FUM meant you could be so unlikeable or disagreeable as to be unemployable and still be financially fine.
