Growing up, I spent every summer in Germany from the time school got out in June until it started up again after Labor Day in my mother's hometown a small city in Lingen. My mom's whole family resides in Germany for the most part and we have kept in touch.

Germany is struggling with immigration and integration more than America. The migration that are largely linked to importing low skill economic immigrants from Turkey to fill low paying service jobs has created three rifts based on religion, ethnicity, and economic class.

This makes it very hard to integrate the Turks as a group into society as a whole. Instead for the most part Turks live in poor isolated urban communities. Like many poor ethnic urban communities, they are breeding grounds for "gangs" who traffic in drugs and violence.

These generalizations and don't apply to every person of Turkish descent. But Germany's challenges are similar to America's, to avoid escalating conflict and violence, children must learn to tolerate individual differences as well as focus on defining and creating a new definition of what it means to be "German".

For German this is hard, since for most of its history, Germany was defined as the land of the ethnic Germans. The US has no similar burden, since except for Native Americans, there are no ethnic Americans to integrate into. We have different issues to deal with along with some of the same.

As a minor side note the challenge of integrating poor ethnic or racial communities is highlighted by the fact, that if you only compare the middle class and upper-class communities of Germany and the US, the crime and violence rates are pretty similar. Poverty has always been a breeding ground for a violent culture, hence the need to focus on providing poor children the kind of education that gives them a chance and hope to escape it.
