> What she meant was that it's impossible to get that rich without doing something bad — without cheating in some way.

She certainly frames it in a way that you have to personally cheat, or personally create the myth that you've earned it, or at least it can be interpreted that way. But I think it is the system itself that causes unearned[1] money to accumulate. Money begets power begets money, with or without any intention of the actors to exploit this is any bad way.

I don't think we know a better system, but I do think we can point to the level of wealth accumulation and say this is a bad property of this overall very good system, and we should try to do something about it.

[1] Or rather: Money to accumulate disproportionate to the earning. We can say that many billionaires have earned something very significant and ALSO say the accumulation is disproportionate to that, and that there is an opportunity here for improvement.
