It's a systemic issue going back decades. To me, it seems the Dutch government always wants to fix it with a hammer. Repeatedly. Discrimination increases, no REAL effort for integration is made (forcing people to take totally-not-racist "civic integration exams" is not an effort), and over the years the divide increases. Tell people they are monsters long enough, and that's what they'll become. But no one wants to hear that fixing it would take years or even decades of sustained effort and change. They just want it fixed. And fixed now.
There is no one magic bullet solution, unfortunately. And then it all comes to a head with the events in Amsterdam. The instigators need to be arrested and tried, but society needs to take a close look at what caused this to happen to begin with. And I doubt that will happen. Just more hammers.
Yes, that's about right. The answer is somewhere in between
