"but deny the evidence of their own eyes - that they can't afford housing, they can't get their DC in schools, can't get doctors appointments, their DC can't get jobs."
Because your own experience are tainted by your own preconcieved ideas, for example if you go to the doctor and there are two people in their who are immigrants then you might, if you had this idea in the first place, get annoyed that immigrants are taking up places in doctors surgeries and causing the NHS to be under too much strain.
The data from several different sources shows the opposite and in a far wider context.
Immigration doesn't cause unemployment, there aren't a set level of jobs, it doesn't lower wages (otherwise why when immigration was growing fast between 2004-2008 did wages rise?), and it doesn't have a significant effect on house prices.
There are far too many sources from different organisations with different objectives backing remaining.
If it doesn't suit big business (the FTSE 250 directors) it doesn't suit small business ( CBI, BCC), it doesn't suit the farmers union, it doesn't suit the car manufacturers (SSMT), it doesn't suit the pharma industry or the medical research one. If the vast array of think tanks and economic organisations are saying that it will be detrimental to the UK, if the Universities and HMRC are coming out with independent data backed research which says the costs of immigration raised by the exit side are either over hyped or simply untrue. Then in whose interest is an exit?
Why are the billinaire owners of the Times and Sun, Telegraph, Mail and Express so keen for it?
Why after 3 years of knowing this would take place is the exit campaing travelling the country with incorrect facts blazoned on the side of its bus?
Its because the paucity of the arguments is startling.
