But at the moment we are far from resource limits for anything save rail transit. As far as I can see taking in about a million people would also only conflict with artificial limits like the Euro financial structure. Germany has what? 2 million empty flats? Also I would submit that the strength the far right can draw from refugees scales very weakly with their number since contact with refugees seems to actually decrease racism.

I'm still very pessimistic. While the wheels are definitely coming off the bullshit train our great leaders seem genuinely unable to deal with it. And in this case they usually default to short sighted misanthropy. Merkel opened the borders in a complete reversal of earlier policy since this was becoming a PR problem for her (#merkelstreichelt), now she reverses course again. All the while we hear about plans to bomb refugee boats, everyone involved in the Syrian war...
Local activism can only compensate for official incompetence up to a certain point. After that will become necessary to throw the European Council into Mount Doom.
