The real scam is that all these H1-B companies grew because American companies laid off their AMERICAN IT guys, especially the more senior ones. Re-orgs, etc.
Topping on the cake, they made the laid off guys TRAIN the cheap replacements if they wanted their Severance package.
The company I work for laid-off hundreds of American workers and imported IT from India. They also set up companies off shore in India to do the projects. Since I am in my sixties now, they have just took everything I previously worked on and sent it off shore. I am now a help desk person supporting new IT software that I was never trained for. It is a job and I have tried to go elsewhere, but I am too old.
