> Some people are very proud of being frugal, spending time optimizing expenses - while earning far less than they could otherwise because they don't spend any mental energy on how to earn more.

This claim really requieres some kind of proof. Because I have never seen this in real life - a person who realistically could earn more if they spent less time trying to save money.

It sounds like a made up dichotomy or an extremely rare situation.

I met people who earn a lot and save absurdly lot. Or earn a lot and waste it all. Or dont ear and either save or not. But, there being realistic path to bigger earnings that is ignored because of spending too much saving is a corner case.
