Recent confusing figures trying to quantify the cost or benefit to the Exchequer of immigration are missing the point.
The important aspect is that a significant number of people in Britain - enough to turn an election - think that immigration has created ghettoised areas where English is not spoken and life not lived in an English way and that this leads to social upheaval.
The non-political class also recognise that these people need public services such as schools, hospitals, policing and so on, costs which don't come out in the figures.
It is not racist to discuss this and if the present politicians don't allow such discussion, either they will find themselves replaced by people who are more normal, or the hitherto silent majority will rebel.
I am just talking about discussing the matter, nothing more than that.
