We had low wages following the GFC, then Austerity, public sector pay freezes, low interest rates and inflation.
Private sector pay isn't going to increase much at all with all of that...
Note though that Director pay trebled over this period.
I live an Cornwall, as area not affected by EU or any other form of immigration, Cornwall voted overwhelmingly for Brexit, despite its EU Objective 1 funding, which has never been replaced, we get about 1/3rd of what we used to get.
I totally understand why someone living in areas which saw high levels of immigration would vote for Brexit but it should also be remembered that the Tories removed the funding given to offset high immigration levels.
People always want someone to blame, even better if a foreigner but the reality is Austerity gave us Brexit, coupled with a remarkably weak PM.
Austerity is at the root cause of almost everything wrong with the UK.
