Things aren’t much better in The Netherlands. The PVV is part of the government now. The good news is that having to form a coalition with other parties, seems to have reigned in some of their worst tendencies. Also, their minister of immigration is a total nitwit that can’t get any sort of actual policy implemented. If they keep failing to make any kind of progress on this issue, hopefully they won’t do as well in the next election.
There are some large, internationally oriented companies where you can get by speaking only English. I’ve also seen more than one tech company hire programmers that don’t speak Dutch. So it depends on the industry.
