In Britain today, many people feel that the good, old things have not been secured and that the changes are not helping them. If they are indigenous, and from the poorer half of society, they are probably right. It is true, for instance, that modern sophisticated societies need quite a lot of immigration; but it is even more blindingly obvious that extremely high rates (we have double the number of immigrants of 20 years ago), which, because of the EU, the Government cannot control, are unpleasant for the poor communities which have to accommodate them. This makes them socially dangerous. If, when you complain about this, you not only get no help, but are also told that you are a horrible person, you get angry. And if you get angry, you are much more likely to vote Ukip.
