Don't be a dick indeed, work more, so you can earn more and pay more taxes for the immigrants (if they were refugees they would stay whereever help was offered instead of storming to Germany), because those loans won't pay by itself and USA, IMF and the banks surely won't write that off.
Right now my country is stormed by them and can barely keep up. Schengen is a joke, same as the EU.
This will probably be down voted since Hacker News turned into a "safe space" (which is ironic considering all the whiplash about free speech on the internet around here), so let me just quote a character called Reality on the popular show "South Park": "You're sad that people are mean ? Well I'm sorry, the world isn't one big liberal arts college campus."
