Hi, tenured professor here! "Professor at GMU" is definitely a scam, but the rest of us work pretty hard.
This site does not whine when someone like Maciej Ceglowski creates a "lifestyle business" that only takes 10 hours or so a week, but it whines when people unionize or climb the academic ladder to get good working condition.
None of them earns as much as a billionaire's child earns just by having parents who gave them a trust fund.
