The parties who are for human rights argue that the poor refugees should come in rich countries because they are poor and have nothing. They believe rich countries must give some of their wealth to the poor, (this means they must give them free health care, free schooling, free holidays ...even the costs of letting the refugees going home to their countries are all paid by the government.) Wow, they don't need to work to pay for their holiday because they are poor.
The politicians are weak in Europe, and because of human rights' protests, they let in too many, by far too many without proper immigration control. Hence, the British freaked out.
Turkey was a key weapon in Leave's armoury and, although claims that the UK would not be able to stop it entering the EU were firmly denied, there was enough uncertainty about this - a fact that the ongoing migrant crisis in Europe unquestionably fed into.
The influx of Syrian refugees and the rest of the immigration crisis—for which there is no end in sight—is changing the face of the country too fast for the population to stomach, and the E.U.’s rules on free movement of labor are an easy target.
When we migrated to Australia from Malaysia, do you have any idea how much effort and money we need to make to be able to qualify the immigration? It is hard to explain to somebody who does not have the same mentality, because in many European countries there is no such thing called business immigration. Malaysia also has it's share of religious problem, and just because we are able to control it better, and that to seek a better life overseas, we must pay a lot of money and so on to compete with others to migrate. This is all because we are NOT poor enough *roll eyes* to be considered as "refugees".
I think the British think differently than the other Europeans. In particular, I think they are less of a socialist than the French. As an Australian (Malaysian born), I can tell you that our left wing is like the French's right wing. Being born in a country who is a member of the commonwealth ( meaning we have a lot of contacts with the British, and that immigration law in Malaysia is very strict, this seems to be a Anglo Saxon influenced system) and lived in Australia since I was a child ( more contacts with the British because Australia has a lot of British) until my marriage to an European, so I moved to Europe ( many contacts with the francophone Europeans) as an adult, I think the British, they are also different from the other Europeans in their mentality.
