I am always baffled by the assertion that 'stopping all immigration would be bad for the economy.'
Why?
Most recent immigrants place a huge burden on the economy; pressures on the NHS, housing, benefits, infrastructure etc. And yes, there are nationalities that are a particular burden, some not so much.
For everyone who says immigration brings financial benefits you can find someone who proves the opposite so goodness knows what is the bottom line.
Why don’t we have a moratorium for at least 2 years and see who or what we actually miss?
