Not informed about NL politics, but would any government be hindering high skilled legal immigration? In my experience this type of migration is highly encouraged, regardless of the left/right leanings of a government.
Many EU countries are only good at attracting exactly the kind of migration that isn't beneficial to economy.

Less migrants, or at least looking like you're trying to have less, tries to get the populist vote.
Tax breaks for well-paid foreigners are difficult to justify in this political climate, and have been reduced substantially in recent years.
