And I take it physicians, lawyers, dentists, and other professionals, on top of all of the entrepreneurs who have sold their beloved companies for millions, aren't doing meaningful or engaging work. If you're good at any of the careers I just listed, you can easily make at least $300-400k+ per year. It's attainable, and there's a ton of meaningful work to be had at those levels.

Success and meaning can be found at levels other than the dude settling for $20/hr because he gets good free time to really 'discover' life and find 'meaning.'

Maybe you're hanging out with the wrong people.
