> You didn't earn that $1B through continuous effort

Why does it have to be earned through continuous effort? It seems like you’re defending a sweeping assertion (that you can’t “earn” $1 billion), but retreating to a narrower position based on a very specific definition of “earn.”

Yes, you can’t become a billionaire performing fungible labor compensated on a periodic (hourly or annual) basis. But I don’t see why that’s the dividing line between “earned” and “unearned.” A lawyer charging hourly will never become a billionaire. But there’s been a couple of lawyers (Joe Jamail, Mark Lanier) who became billionaires by securing enormous verdicts for their clients. Are you saying lawyers “earn” their money only if they charge hourly, but not if they get a share of the money they recover for their client?

That seems to be a weird definition of “earned” versus “unearned.” Maybe you can say that money is unearned when it’s inherited. Or that it’s unearned when it’s just accrued interest. Or that it’s unearned if it’s through socially questionable activities like high frequency trading. But most billionaires didn’t get their money in those ways.
