The government curbs immigration, job vacancies don’t get filled as there’s a shortage of immigration to fill those positions, that forces productivity down, that forces a shrinkage of the economy. It’s basic maths. No government is going to stand on a menifesto of deliberately shrinking the economy whether the PM/party leader stood on a manifesto of taking back control in a referendum, in a party leadership campaign or indeed a general election whether they’ve been ranting about taking back control for the last 4 years or not. In other words nothing is going to change in terms of immigration numbers for the simple point that the economy demands immigration. Unless you deliberately shrink it by blocking immigration. The only thing that’s going to change is the demographic of immigration and as the chart shows brexit is going to cause smaller numbers of the demographic that contributes to the treasury and that is going to be replaced by the demographic that tends to cost the treasury.
We spend £360M a week on EU membership, let’s spend it funding a different demographic of immigration that costs the treasury money to keep the economy going post brexit instead. They should have put that on the side of a bus.
