And at the same time we can sneak our communist smiles into the West. So there were some positives of keeping that wall open. But the biggest negative is there's a humongous brain drain. Over half of these defectors are what you would be considering the intelligentsia, kind of young people that have, you know, spectacular careers ahead of them. And they're looking at the life in West Berlin, and they're looking at their life in East Berlin, and they're saying, standard of living is pretty good over there. I want to go over there.
