All of them would have to obey minimum pay regulation. If Apple knowingly hires a company violating that law, then absolutely go after them. If loopholes come from that regulation, then that has to be fixed too.

For someone who works on site at Apple in Cupertino, the minimum wage is not a liveable wage, even with four or eight to an apartment. We could try a per zip code minimum wage, that would even raise teachers' salaries, then we'd need a per zip code tax for public employees. Or some other solution. http://www.mercurynews.com/2017/04/22/in-costly-bay-area-eve...
