Would freedom of immigration go a long way towards ending human trafficking and sex trafficking in particular?
If it was easier for people to immigrate to wherever they wanted this would close off the flow of people for traffickers to exploit, and if anyone could leave a trafficked situation without worrying about being deported, not being protected, not being able to work legally etc.. this this would reduce the hold that traffickers hold over them.
There are good economic and social justice arguments for freedom of immigration too. Would you support open immigration to the UK, and accross the EU?
