Yep, that lines up with what I've read and what I've personally experienced. Beyond $75k (or your local currency equivalent), more money is more of a theoretical "can do more nice things", "drives a nicer car", "can go skiing for holidays instead of rent a beach shack." It's nice, but it's a change in degree, not a change in kind.

Below $75k combined income is where those "do I want X or Y because I can't have both" situations come about increasingly frequently. Below $45k it becomes "do I want to pay the electricity bill or the rent?"
