You're speaking of immigrants assimilating into Dutch culture by speaking the Dutch language and increasing their skills, presumably to fit into the majority Dutch workforce and to fit in better with "Dutchness".
This describes the American view of immigrants in the past, where Irish and Italians where expected to learn English and conform to American culture (working hard, showing up to work on time, etc). In the new Woke era, assimilation is considered a cruelty towards immigrants, especially those "of color". Moreover, assimilation of current Black citizens is considered cruel as well.
This is more easily understood when you research how the media, democrats and school systems define "whiteness".
An American leftist would ask why the Netherlands is being so cruel to immigrants by teaching them Dutch and expecting them to assimilate: Why is the Netherlands forcing their majority culture on immigrants of color? Sounds very imperialist and elitest.
That is a new movement, in the past bad choices were made and sadly those decisions were made by fiscal conservatives and religious conservatives. In a team of great expansion of the Netherlands we needed workers. And in their infinite wisdom the fiscal conservatives of the VVD and the confessional parties (Roman Catholic and protestant conservatives) ARP, CHU, KVP, went to Morocco to get their new workers. They have 2 choices:
1. take workers from the coastal regions of Morocco. They were better trained, most knew French, had better educations and were "more liberal" (but still not actual liberals)
2. take workers from the Riff mountain of Morocco. They were hard workers but most of them just knew Arabic, were less educated, a lot of them were not able to read or write and were more conservative religious people.
Well a smart country would have chosen option 1 but guess what, the Fiscal conservatives and christian parties that formed the government chose option 2. A lot of them were not even able to sign their names on the immigration agreements.
So that was the first mistake. The second mistake deciding to not give these new immigrants Dutch lessons. The government (christians and fiscal conservatives) decided that as soon as the need for these immigrants was over they would go back to their countries so why waste time and money teaching them the Dutch language. The little they needed at work they would learn on the job. But the booming years did not really die down that much. So the need for immigrants stayed. Then came the continuation of those poor choices. They had their wives and children move down to the Netherlands too. Also poorly educated, women were mostly not allowed to leave the home without their husband, very islamic and again, not forced to learn Dutch.
By the time they had been living here for 30 years and having become Dutch citizens they could no longer be forced to learn Dutch. Their children as said suffered from the lack of Dutch speaking role models and it has taken to the second generation for that to be less of an issue. In fact now the issue is that most of these kids barely speak arabic any more. Which is an issue in the mosques because most younger faithful are unable to understand the arabic preacher.
Now immigrants have to learn Dutch, that is all except the Turkish. That is because of a deal with Turkey, they cannot force our citizens to learn Turkish when they move there and vice versa.
Another problem that the (sadly again the fiscal conservatives and christians parties decided was that Morocco was granted access to our citizen database. This has caused an issue with people with 2 passports. Any child born in the Netherlands were one or both parents are of Moroccan descent/in possession of a Moroccan passport, automatically because dual citizens. Not only are they Dutch citizens but without the approval or wishes of the parents, these children also get a Moroccan passport. Which is also stupid as hell.
