I see what you’re saying but I don’t think you’ve closed any gaps. If leanfire is bourgeoisie at $300k, then people with the same amount of money who are working instead of retiring are choosing to work, just like Musk.
I get that it shouldn’t be a net worth calculation, but that’s really a stand-in for the conundrum that occurs when someone could retire but isn’t, and who gets to define what “could retire” means. Is someone staying one extra year in the coal mines to pay for their granddaughter’s college in the bourgeoisie for that year? Does it matter what the goal is? What about staying multiple years? What if the goal is making enough money to launch a mission to Mars? I’m back on Musk.
You’re either setting the definition at literal need, in which case you’re making a pretty huge bourgeoisie of whom a large percentage work for a living, or it’s just fuzzy because you need to know interests and intentions and internal thoughts and feelings.
