When I fulltime consulted, I would often do something similar between clients. Never liked it as it remove time for education, reading, thinking, family / friends etc.
The breakdown is that he has one fulltime job of 140k + 80 hours a week capacity for 75 USD. If he saturates that, he is working 120 hours out of the 168 hours there is in a week, ie. under 7 hours of sleep while still working weekends and no time for other activities than work also excluding eating, toilet visits, etc.
Whether this is misrepresentation or legal, we would need to know the contracts of. But unless these are made by companies overly in favour of him, I doubt. Especially because he does not do anything specialised (75$/hour is in the low end of commodity software development).
Personally I would rather spend time specialising in a craft that pays better and work less and increase the potential hourly rate rather than the potential yearly income.
