EU has very strong employee rights, so that will come to the same point as a union in the US. The lower pay is an advantage but the time zone difference of 8-12 hours can be a disadvantage. There are no language barriers in IT between the US and Europe, by the time they graduate college the average European has gone through more than a decade of English courses. Cultural differences are minor, management style is very similar (in the East) and so is the communication culture.
So yes, lots of American companies already outsource to East Europe. There are lots of "Silicon Valley"s across EE thriving on Western outsourcing from companies who aren't quite desperate or cheap enough to go to India.
As simple rule of thumb an employer in the EU has to pay roughly double the net salary amount, so on top of the salary pocketed by the employee yet another similar amount goes to taxes. The education/insurance aren't "free", they're just managed better and give more direct benefits to the taxpayer.

That requires following due process, the presumption of innocence, and observing the right to privacy. You have to convince a judge, in the context of the existing laws, that a certain individual or group are suspicious enough to call for (specific) further investigation.
Mass surveillance and forcing weak encryption bypass or overturn all that. It's a radically different view when you assume everybody is guilty of something by default and that they have no right to privacy.
