Don’t take this the wrong way please, I don’t think you know what the working classes think nor want.
They don’t want socialism, they have a huge degree of patriotism, support the royal family etc. they want Britain to be independent of the EU, as you’ve mentioned.
They want investment in their areas and infrastructure to work but aren’t jealous of the rich, as Labour think they are, they want the opportunity to become rich themselves.
They want immigration to be curbed and for their communities to continue as they have done socially, in years gone by.
They want the UK to be strong on defence and law and order.
They see Labour as a threat to all of the above and middle class wannabe socialists don’t get it and they have no respect for them.
The metropolitan left are completely different to the northern heartland left.
