People's desires are so miscalibrated that the only way to get long-term survival for the human race is for people (including those at the top of the status ladder) to have more of a sense of duty than anyone now does.

What does that have to do with being so miscalibrated? Certainly having too little sense of duty would be just as miscalibrated as having too much. And it's not like having a better-calibrated sense of desires would change what other desires would work.
