They do all sorts of nonsense. They regulate the trade between EU nations as well as the trade between nations who are trading with EU nations. They prevent individual countries from importing goods on their own that don't meet their weird as fuck standards in addition to imposing tariffs. They'll also take payment from different wealthier nations and redistribute to the poorer countries (see Greece and other nations). They're also involved in the migrant crisis because Angela Merkel took on millions of "refugees" who turned out to be migrants and then assumed all of the other countries would take them. They regulate travel between the countries, enforcing a free movement policy which allows any citizen with an EU passport free movement between the countries (so all those lovely migrants move to the more welfare-rich nations in the EU after landing in the welcoming countries). They're also attempting to regulate the linking of content throughout the interwebs. Because the lefties can't meme and are butthurt faggots who are losing ground.
I'm just disappointed that it's all so fucking repetitive. Change it up a little faggots, we're getting desensitized. Hey, try some CP and get V&. It'll make ya feel better. Then your oppression will be REAL.
