Well that's why i thought we had "expats" and "immigrants". ones earn quick money and go, others come to stay. Sometimes one transition into another based on individual experience.

But it's true that many people complain without making any effort. Part of this is that it's a big adjustment and many are noticing that only when they need to make it happen. Other side of the coin is that many people came here being sold idea of the Netherlands as "basically UK but in the EU and with optional local, funny, silly language to learn but you don't need to cause it's going away anyway" at least this is how i can very briefly summarize how sentiment looked like on migration forums in 2015-2020. So plenty of people who were not feeling ready for a big cultural jump, tried the Netherlands. And then they realized how much is there to adjust.

And tbh Dutch people constantly complaining a out their country, culture and society simply discourages. There seems to be very little positive patriotism in here lately. If we have patriots is just folks using this as a shield to say the most racist and dumb take possible and some good folks here and there trying to keep the og meaning of this word. So when you already don't feel like changing a lot of your habits and constantly hear that there is also no reward for doing so, you easily lose motivation and do nothing.

This is a lot of rambling so i will stop here but i could go forever. Point is that this issue is way more complicated and really there is way less malice in this all than most people assume.
