I think we should be careful. It's certainly true that greedy powerful people in the world today are getting increasingly aggressive about seizing more money and power, and that's terrible, and we need to do whatever we reasonably can to stop it.

I don't recall seeing any data that suggests the average level of greed among the general population has grown, or that the average desire to work among the general population has gone down.

The reason this distinction matters is because when someone makes the claim that too many people are greedy these days, it sounds like a problem with the general population, when what we're actually seeing is a problem with the ultra-rich.
