BTW, I totally disagree with the notion that high pay is the reward for hard work or even education (I can show you many hard-working PhDs who make very little money).
Seems to me that high wealth/income is most closely aligned with proximity to those who control money flow. Those who have the money, control where it flows, and vice-versa. Extreme wealth has very little to do with “hard work” or intelligence (other than knowing how to scam the system). The fact that cap gains & dividends are taxed at a lower rate than labor is a great example of this.
