One issue amongst the immigrant population near me is one that I'd like to see better addressed. I live near a very "deprived" town with a high immigrant population, and an overwhelming majority of the English residents voted Leave. It is an area associated with high crime rates and has a reputation as being full of non-working immigrants.
In reality, several articles have been published in the last year, highlighting the amount of human trafficking and slavery in the local area. Gang masters have lured people over with the promise of work (far less than is available for the number they bring in) and confiscate passports on arrival. They rent from unscrupulous landlords, and pile them in, 10 to a room, charging them for lodging. They provide transport (for a fee) out to work sites, where "Sorry, We can only take half of you guys today. BTW, you still owe for the transport and accommodation- so now you're in debt to us."
Since they have no wish to go back to the cramped house, you can see some of them hanging around the local parks during the day.
They can try to work off their debts, but it often involves illegal activities. Sham marriages to people outside the EU. Prostitution. Drug sales.
And since the local English population resents them, where can they go for help?
I don't want them out, but I would like more resources for people who fall victim to trafficking and harsher penalties for the people exploit them.
