It's not such a great problem that the UK chose the Brexit, to leave the EU. It's not a problem to use the passport instead of the visa that people receive at some age(in my country we receive it after the age becomes 14). Well, on the bright side, the British Pound will become less valuable, maybe at the state of the Euro or of a dollar, and that means more shopping opportunities for some people who have Euros or other currency. I understand the illegal immigrant problem, but don't involve legal hard-working people, as well. Kaze said on the topic that "Romanians build masions" after 2 years in the UK. Totally FALSE! But, you do know that the Brexit will not be overnight. It will be after some years, maybe 5, maybe 2, maybe 7. So, you still are in the EU for some time. Oh, yes, people have to blame something for bad things. 40-50 year-olds in my country(Romania), blame the EU for turning their country into a country without factories, that has to import "s**t"(that's what they claim in private, in their homes and in their minds). Many Romanians think that communism was way better. We know that always new things are "CRAZY" for many people, but it doesn't mean that it is worse, nor better. Nostalgia wouldn't bring back the past or bring a new hope. The only factor to decide is the avarage unaware citizen, who likes to blame someone for everything. Iliescu was the biggest mistake in Romania, and we can't go back in time to fix that now. But, it doesn't mean that the citizens need to make boring protests and complain on Facebook(Sorry that I went a bit off topic). So, the UK can become a better place for everyone. Maybe you should start considering other jobs than the ones everyone want. Why don't you try working in cleaning the city or some farming? It never hurt anyone. But it doesn't mean that you have to leave uneducated people become sewer cleaners, street cleaners, farmers and so on. Oh, and don't try to put nationalities at some level. Citizens of a country are different, so, it doesn't mean that all Romanians come to the UK to be lazy.
Oh, and maybe, instead of talking on this topic, maybe the British players of Argonath could go on the streets and see what the real problems are, then, try to think of solutions with the communities around them. I'm just saying. Oh, and, I appreciate that the British care about voting(75% of the British citizens is a lot). Meanwhile, when Romania had local elections a few weeks ago, the voting count in the whole country was around 44% or so(not even 50%), and most of them were people around 60-80 years. So, no wonder they chose bad, only the people they have heard of or they have seen on propaganda news channels(those aren't supposed to be on TV, at all). Sorry again for going off-topic.
To end this, I think that it won't affect the EU that much, and that the EU should rethink its' rules and plans, and the British to try to be more understanding and to know people better. Oh, and to kick out all the illegal immigrants, who didn't come with any paper with them. Some really need to be kicked out.
