I don't know what you call the opposite of "right to work" but that's basically the employment situation H1B's find themselves in. My Fortune 500 clients have office building upon office building of H1B developers. These folks will do practically whatever it takes to keep their employer happy. They are afraid to rock the boat and have their family sent back to India. This means bad decisions go unquestioned. You can guess what the result is.
You have put your finger on a key pathology of software development in general, not just H1-B: Mediocrities with terrible ideas about software love to have their bad ideas implemented without question. This explains why companies can easily end up paying more for H1-B labor. Egos get stroked. Nobody is asked WTF. Bad software is piled on top of bad software.
Not only is this a source of wage depression and age discrimination, it results in the kind of horrible-but-expensive IT that runs banking, health care, government, etc. and makes it much harder than necessary to apply technology to reforming those sectors.
This is true for H-1B's employed by outsourcing companies. It is generally not true for most other H-1B workers who are treated identically to other workers.
