I doubt there are many talented engineers among the millions that crossed USA border recently. Same goes for Europe.Ok, since most of you seem unfamiliar with current Dutch politics. The issue here is that the Netherlands is going down the path of national conservatism (Trumpism if you like). So tougher laws on immigration, no special treatment of expats. ASML doesn't like that because the right wing identity politics doesn't get you talent, just like the left kind doesn't.
That skilled engineer you talk about supports those with his taxes. Immigration as we know does not convert into skilled workers but becomes a burden for country's budget. To let more talented people in, there has to be a narrow aim, a set of laws letting specifically those to come.
I am very tired about how people talk about these issues as a whole. Immigration, minority groups, etc. They are people, people that can be worthy and good or bad.
Netherland has bad immigrant laws? Well maybe because people saw the results and started to vote for more radical politicians. They do not appear out of nowhere, but when people are upset with previous government.
