Honestly, I don't see that much different from a hollywood actress or NHL player being paid in millions. Which might be seen as a moral issue but a different one, of equal renumeration for work.

But it's important to point out that main source of income for B.G. (or any capitalist, for that matter) is not a reward for work, but rather reward from ownership of capital, which is essentially a share of economic decisions. It's pretty unclear to me why the society should reward ownership and not just work.

Society should reward good stewardship of owned resources, as well as good work.

Stewardship is not ownership, though.

A king, an absolute monarch, effectively owns the country, and his position is hereditary. A prime minister does not own the country, despite "being in charge", and it's not hereditary. People overwhelmingly prefer the latter system.

I don't see why business (economic production) should be any different.

Ownership of capital is not stewardship.
