People can make money through success in positive sum games, which wouldn’t require exploiting other people.
There are poor people who make money through rent seeking too, by playing zero sum games. These zero summers should be targeted rather than the entrepreneurs, artists, writers, and musicians who play positive sum games.
It’s similar to how we benefit from cheap manufacturing labor in other countries, performed by people we don’t know. Who did we underpay to get our luxurious lifestyles? The fact that we can’t name them is part of the sleight of hand that allows us to ignore the exploitation, but it doesn’t mean it doesn’t exist.
This is actually completely wrong. Believe it or not, many of the richest people get rich because they pay their employees more than they think they are worth.
That's why I said worth not value. You can define what a person thinks they are worth by asking them.
The reality is, the impact of a wealthy person is almost always small, and usually negative-on-net. That's why, in the thousands of historical examples of titanic changes brought about by new ideas or state-level policies, we have so few examples of wealthy people changing things for the better.
