We allow Europeans come to this country indefinitely without a visa, while Arabs and Africans might find it impossible to get a visa even to visit.
Where you come from has a huge effect on where you can travel to and where you can live. It's the biggest single factor affecting your freedom of movement at an international level. How on earth is that situation not racist?
You really think that it's about people's race? Of course it isn't.
There are many countries outside of Europe that we would need a visa to visit and would find it almost impossible to get a visa to stay over to reside or work.
Even for India, we need a visa to visit the place, yet they don't need a visa to visit the UK. Unfair? Yes. Racist against Europeans? No.
Pakistan for example, it's impossible for any of us to live or work there - there is no immigration into Pakistan...period. Unfair? Yes. Racist? No.
Japan. Almost impossible for anyone outside of Japan to get a right to reside. Unfair? Possibly. Racist? No.
There is a reason why someone opposed to mass immigration wants the UK to pull out of EU...it gives us the chance to halt the whole bloody lot without anyone implying that the UK is racist.
What's the largest group of illegal immigrants in the UK? Australians. Do you see home office campaigns focussed on driving out all the aussie visa overstayers? No, because they're too busy raiding chinatowns and African communities instead. Why is that do you think?
There is no "Aussie town" in London, the Aussies could be working absolutely anywhere. A raid on a place like Chinatown would be low hanging fruit for the Border Service (or whatever they are called these days.)
Also, an Australian at some point is going back home. They aren't staying here so they can send money back home, they are overstaying because it's very much fun and they don't want to go home just yet...but they will...because they'll be missing family and friends.
So getting back to it - it's money. We all know the reason why people risk life and limb to come here...is for better economic prospects.
We all would migrate if we could. If I could land a job in the U.S. or Switzerland for 4 times as much, I'd be off...if they would have me...but if they won't have me...well...I have to respect that.
