In general I agree. It's just that I don't know if salaried job lead to FU money. The only person I had or will be able to say FU is to myself sitting alone in living room.
Depends on who you are and what your growth potential is. I know SWEs getting offers in the 7-8 figure range. That's not in any way typical but if you're smart enough, hardworking, and get the right breaks hitting a 7 figure income isn't something I'd consider weird and is definitely FU money.
