From what he says, it looks like he gets $40 to $60 per job, whereas cleaners get $15 to $30 per job -- they work in team, so it's $30 to $60 in total (it's all pre-tax, from what I understand). Not a terrible arrangement, to be honest, especially in the Land Of The Free From Socialism; apparently this is much more than what they used to make when a big company exploited them.
I do agree however that the IRS will kick the shit out of him if he doesn't switch to proper employment asap, and that's how it should be: it's all fun and games when things go well, but when hard times come (and they will come) the workers should get some protection.
