I am not anti-immigration, but like most of the population and every political party, I think the current rate is too high.
While it benefits government, employers and the rich, the deleterious consequences fall upon the poor.

I am not aware that any party has "reversed its views".

The Blair/Brown governments encouraged immigration.
Members of that government have since admitted that they allowed the rate to get too high, with harmful consequences.

There is a case for and against high levels of immigration.
To have an informed debate, both sides need to be put.
May put the case against.
Why do people object?
