Breaking up ghettos is very difficult if for no other reason than the people that live there want to live together.
France already has active policies to try and avoid such ghettos to start with, where new developments are obliged to provide a percentage of low income housing as a part of their project. The idea being to spread immigrants and other poor amongst wealthier native communities.
So long as the percentage of immigrants is low, this works. When it gets too high in a concentrated area, then we have a ghetto again just in a different place. The higher the percentage, the less integration.
Current immigration policy is far too open. Once one single person in a family gets papers, often by measures such as buying a spouse for the reason or, more common in my experience, tricking westerners into getting married (including trying to get pregnant by the westerner while they're there on holiday, for example - had that tried on me twice), then the rest of the family gets papers, and then more family and more family and more family, etc.
Islam needs to come forward through a renaissance age but it's not happening.
I'm not sure what perspective you propose to give people who blame us for anything that's wrong in their lives, whether it's our fault or not.
Where do you draw the line? Today it's our right to free speech, what follows? Our women having to be veiled? Our girls not having the right to go to school?
