I have no strong opinion on the working multiple jobs thing, but a single person making $140k is not forced to do anything. That is not a low wage. Fucking hell.
Seriously, a single person making less than that can live comfortably nearly anywhere in the US if they keep expenses reasonable, especially if it's remote and they have no need for a car
yeah, just a quick reality check for the codezillas here: The median US household income for 2021 was $68,000
