What do these people owe the world? Nothing. How much net positive does the average person due to for the world? Not much. Are intelligent people your slaves? You mean some smart person who's done some good for the world should be ashamed for trying to afford good schools for their kids? That's the worst possible attitude.
There are plenty of ways to make a living and still be a net positive for society. I wasn't shaming him, but I'd love to raise my children in a culture where the focus is helping not just yourself and your possibly undeserving offspring (e.g, the university bribery scandal or countless other instances of corruption), but the rest of humanity as well. I think we'd all be a lot better off.
