Absolutely I’m willing to agree to that.
I am only pushing back on the statement, “it is impossible to amass a billion dollars without exploiting the labor of the working class.”
I certainly don’t think that’s the majority of billionaires. If your definition of exploiting the labor of the working class includes “having any employees that aren’t part owners of the business,” then of course the number of billionaires who can say that is vanishingly small.
But they do in fact exist, and I think the majority of people are aware of that. Therefore, making statements like “all billionaires exploited labor” makes the average person think your position is uninformed at best and disingenuous at worst.
