Then the "intelligentsia" deserve what (hopefully) is coming, because they have been the tail wagging the dog.
Rather than blame the working class for their desire to give the establishment a bloody nose you should look at the political conduct of the establishment.
It is telling now that even those in the remain camp are advocating reform of freedom of movement, proof if it was needed that politicians cannot be trusted to act in the people's interest.........they have to be dragged and forced.
They are reaping what they sowed.
And what exactly is coming for them. If there is a Brexit vote, then any downturn in the economy isn't going to affect them, they are insulated from the financial problems due to their wealth. It's going to affect those at the other end of the scale, just as the depression in 2008 did. An example could be if you are coming up to retirement and have a pension fund and have to buy an annuity to pay your pension for the rest of your life. Downturn in stocks and shares will reduce your fund and I'm guessing any annuity you buy might pay a lot less!!! That could be your earnings for the next 30 years!
Furthermore, the expected downturn will affect tax receipts and, ergo, public spending. Who suffers then.
We've heard that Brexit think a deal with the EU can be done by May 2020. 4 years and that is likely to be an optimistic target as is the two years to negotiate an exit from the EU.
