The fuzzy part is picking an amount to consider “enough to live off of.” Elon Musk still works, it’s not a question of if you are currently working but a question of whether you need to. But some people “leanfire” retire with $300k in stocks. So is everyone with a net worth of $300k or more part of the Bourgeoisie?
And apologies to the true theorists because I’m sure Marx covered this somewhere but this makes me wonder about the elderly or unfortunate living off of government payments like Social Security with zero net worth…they don’t work to survive, but they don’t have any money.
