I found this over at LL's place. It seemed like an excellent way to illustrate the problem of immigration, refugees and displaced persons, so here it is. Watch it in full-screen mode for best results.
Someone should show this to Frau Merkel and the other Eurocrats agitating to let unlimited 'refugees' (AKA economic migrants) into the European Union. They might learn something, if they were prepared to listen (which they probably aren't).
