Saw that. The problem is, can't put the genie back in the bottle. I was in Berlin last week. I didn't exactly see evidence of any cultural issues. I did spend some time bullshitting with local Germans about it, they didn't seem all that concerned about it. They did say that Berlin didn't have many of the problems some other German towns had.
First thing I look for, but I didn't ask earlier because I'm a bit rusty. Good time to look at "destroyed" Germany's PPP for the last nine years.
