Can you imagine Saudi Arabia letting in 2 million Christians?
Blame your brits, if they wanted to work in low paid industries there would not have been necessary to reach for immigrants.
But now, britons have always felt superior and though it is humiliating for them to take these jobs, they have always wanted to conquer other who work for them as lower class, and brits will be upper class.
This class system is alive and well today. So don't blame foreigners, blame your natives and govt who did against you.
