This is my point (not about race, that is just plain racist). Many immigrant populations come here with nothing. Even poor families that have been settled in the UK for generations have some wealth in the form of housing or education, but immigrants start right at the bottom, and for many, getting on that first rung of the ladder is near impossible. Race of immigrants really has nothing to do with it. Otherwise, why are there so many poor white people living in trailers in America or Australia, or indeed, many parts of the UK? If you want to see poverty in the UK, head to your local traveller community - there you'll probably meet some drug gangs too, along with many hard working people who are trying to improve their lot.
Take me for instance. My great-grandparents on my mothers side were Irish immigrants. My grandfather on dad's side was a tool maker. None had any wealth, none owned property. The first person to own a property in my family was my dad, when he bought the house my grandparents were living in so they did not get evicted. He manged to get a good education at the local grammar school, and became an accountant. My mum went to the girls high school and got her dream job of a secretary. Education totally changed their lives. By time I was born, they were relatively wealthy and could afford to support 3 boys in their education. Jump back 2-3 generations and if you met my family you would probably say "gypsy scum, get a job".
The biggest problem we face is fighting this idea that people of different colour are the problem. Society is the problem, and we help shape the society we live in. It all starts with secure homes, education, good jobs, respect. Nobody wants to live a life of crime, but for some, it is all they have. Many people in this country want to keep people down though, that is the real problem.
