EU referendum, brexit and the aftermath

Ideally, I would like a world where we don't discriminate people on the basis of where they happen to be born or raised, where you can as easily relocate to another country as another county and where we achieve common good through co-operation and collaboration. There are aspects of the "modern, global world" that bring us closer to that ideal (EU being one of them) and aspects that work against it (regressive nationalism, global corporations that outpower governments).
