It's really hard to have a sensible discussion if you are going to ignore what I am saying. I addressed EXACTLY the case you highlight in my comment. EXACTLY. Here's a quote from the article you linked to:
"On a morning last May, Jing Ren, a 20-year-old who had recently arrived from China, stood among them for the first time, headed to a job at a salon in a Long Island strip mall. Her hair neat and glasses perpetually askew, she clutched her lunch and a packet of nail tools that manicurists must bring from job to job."
As I said, this is an IMMIGRATION problem, not a labor law problem. The labor laws are already there to cover this. They are simply not being enforced. However, I'd be willing to bet all of these people are illegal immigrants being abused by their own kind. In other words, exactly what I said in my comment.
Exploitation by reputable companies does not exist in this country. Only sweatshops, generally ethnic, are likely to take advantage of and abuse illegal immigrants, which, again, is a failure in immigration law. In other words, here is a picture perfect case of our government actively harming people for not taking measures to ensure that immigration happens in an orderly manner and will full protection for those who join our ranks.
Why do "reputable companies" have compliance departments if no one obeys the law for the sake of obeying the law or avoiding punishment? Think a little harder.
This is patently, demonstrably false. Here's one example, but wage theft and illegal practices are far from dead: http://www.nytimes.com/2015/05/10/nyregion/at-nail-salons-in...
