You should try hiring once, before dropping such simplistic statements.
The upcoming H1B squeeze won't help. White CS grads do. not. want. to work in boring tech such as QA, etc. Remove Eastern Europeans and Asians and we're back to outsourcing whole departments to their home countries.
That's reality.
The US is utterly failing in creating enough homegrown talent, university education is far too expensive, everything below is useless as there is no good education available below.
Just a little bit more and some other country/region will take that whole business, that's how the economy works. Unlimited salaries never happens.
