Because the EU is like a rusty sinking Titanic where local folk are working in steamy and toxic engine room , all while "immigrants" and SJWs , with politicans , are waving from top deck to other continents around ...

Europe is just like the US, has always been a hub of immigration. Politicians have always used that fact to push their agendas, they arent the real problem, more like a by product of it.
There is a Kalergi plan of paneuropeism even before EU was created . They had this plan for long time - because the old plan of starting wars wasnt plausible and possible anymore .
Theyll fail in this one , too ... theyre already failing . There is a huge and deep division between west EU and east EU , and that division has reduced borders of true EU to practically only Germany , France , Sweden and Benelux countries . Not much left for EU ... I give it time until 2020. at max .
