- correct, the key word in your sentence being *back*. Back is where they would have to go in order to get away from these 'horrible companies' that are giving them something they never had before - a choice of not going back, from where they came.

No one is holding a gun to their heads to force them to feed their kids and have basic shelter.
- precisely, nobody is forcing them to eat and to feed their kids. They are choosing to do so by working for the companies that are offering them these jobs. They can go *back* of-course, back from whence they came.
