We can play this game all day, but the fact is somebody put a ton of work into a project and made about what they could have made in a month at a FAANG.
Not really. FAANG people have to show up to get that salary. It's not apples to apples to compare this to salary because the app was built once then continued to make money without additional work.
Salary requires constant effort and work. I will take working 60 - 80 hours for a week to make $40k over working 320 hours to make the same.

Pretty crappy trade off.
