"can do things others can't" isn't the thing we want to stop, though. Wealth isn't bad for those who focus on creating value, just as strength isn't bad for those who are in the gym 6 days a week.

It's not healthy to a democracy to have power concentrated, because invariably it leads to a less diverse set of opinions on consequential decisions.

Even if (and big if!) we say that wealth/power-alone doesn't make people think differently, you're sampling from a much smaller population.

And I'd need some convincing on "I don't know how much a gallon of milk costs" not changing a person's perspective.
