Clearly your country's immigration system isn't labyrinthine and bureaucratic enough. Add enough systematic hatred and anyone can be turned into a burden to society.

Here in the Netherlands, immigrants are not allowed to work, so everything has to be provided to them by the state. The construction industry has been regulated and defunded so that building houses for the lower class is never profitable and is only built through quotas that are too low to meet demand, leading to immigrants competing with locals for extremely rare housing, leading to abuse victims being forced to stay with their abusers or go homeless. They are not taught the local language and children have to go to segregated schools to prevent them from forming attachments. There is an army of bureaucrats, cops, lawyers, judges, and public defenders involved in determining whether they have the right to stay, regulating how they live, enforcing how they live, litigating how they live, appealing litigation, and going after immigrants who are required to leave.
