As abhorrent as the situation is, the body shops are only taking advantage of a legal windfall that American corporate greed has lobbied for. The system has been rigged. You can't completely blame the actors taking advantage of it.
Right, so you are driving along in the middle of now where and come to a red light. You know that the likelihood of a police officer being around is very slim. Do you wait for the light to turn green or do you just go through the red light?
These companies are going through the red light. They are intentional manipulating, gaming, and deceiving in order to make huge profits off their own country people by engaging in nothing more than 21st slavery.
The companies that hire these body shops have the old bait and switch pulled on them. The first initial consultation the A team developers are doing the work. These are ones that are paid on par or higher than their native counterparts. Then the company pulls out team A and sends in the 21st slaves. And you don't think the company that thought they were going to get the A Team developers for the duration of their project instead of just the first month, is because of their greed? That "greedy American corporation" is still paying the 5 million dollar contract. But the body shop, they just walked away with 4.5 million dollars. Who is greedy here?
We are just advocating reform and change. The loophole has been leaking for such a long time. Obama knew the problem a long time ago and did NOT fix it. The middle-class wages have been stagnating for many years. The middle-class families are shrinking. A recent research paper found that H-1B visas have kept down wages by up to 5.1% and employment of US workers by 10.8% between 1994 and 2001. Here is the paper: http://www.nber.org/papers/w23153
Technically they are legally (and arguably morally) obligated to act in the best interests of the business on behalf of the shareholders who own it. It's up to the govt. and the market to define what falls under "best interests."
