Against this backdrop, it is perhaps unsurprising that Brexit divided the nation in the way it did. If you were in a relatively well-paid job and not at risk of being replaced or undercut by a worker from overseas, you were likely to vote remain. The Polish plumber was cheaper, the Lithuanian nanny was better educated, so what was not to like?
If, on the other hand, you were part of Britain’s casualised workforce, needing two or more part-time jobs to get by, you were much more likely to vote leave, on the grounds that tougher controls on migration would lead to a tighter labour market, which in turn would push up wages.
For those who have nothing to fear from open borders, labour shortages are evidence Brexit is flawed. For those not so fortunate, it is doing what it was supposed to do.
