Umm, have you been to Enfield? Not down at heel? I invite you to come and take a look at the Island Village estate, or Ponders End, or come just down the road to Edmonton, or any part of Enfield on one side of the a10.
Nice assumptions too.
Did you not se the poster from above that said how actually if the government had acknowledged that Boston's population had incrased ( and it knew this from several sources) and therefore increased fuing it would have been fine and that immigration had positive effects on the town?
See you are desperate to blame immigration for the problem, but in the end it isn't. The problem is fear, now the Tories and their allies in the press have made Europe the bad guy for decades, and since 2004 have been bitterly nasty about EU immigration. It influences judgements, allows misconciieved preconceptions to develop and ends the issues of a small minority within a minority being used to demonise the entire populous, or make judgements on why certain things are the way they are, and then we end with a brexit.
EU immigrants don't steal people's jobs, they are net tax contributors, they benefit the majority of the communities that they are in, there are a minority which don't.
Also when you say Labour didn't listen, well yes it didn't, but because many of the problems that you are identifying with immigration are actually to do with austerity, and Labour spend 5 years fighting austerity, and still does, then maybe they were. The immigration fund should have been highlighted at the election though.
