"Since leaving--wages have rapidly gone up". The wage rises have nothing to do with Brexit, they are coming in to try to reduce the gap between what was earned in 2010 and now.(Tory Austerity, to keep inflation down, remember ? but inflation continued).
There is NO BENEFIT we could have from Brexit even if it had been handled in a better way. If you think there is, list them, I will demolish them.
SBF and Punkie have it right, it's a complete disaster. It was always going to be.
