I think most people in the UK are deeply class based. In addition, I think they trust the establishment. Anyone of middle class or above fear socialism, because they see it as taking away from them.
The working classes are kept down, through inferior education. Even as a teacher, I see this as deliberate policy. So many hurdles are put in the way of the educational system, there is no way it is by chance. If the minds of the workers aren't developed, they don't have the analytical skills to see that 'the establishment' is NEVER going to help them. That the right wing is only out for itself, as we can see now with the current government.
In addition, the establishment have SO much money behind them. They can afford a horrific media campaign and have no compunction about lying. Power is all, to them. Once in power, they can do what they want, until the next round of election lies.
I will never live to see a government which really has the welfare of the people they are supposed to represent at heart. I fear we are heading back to an extreme right-wing to rival that of the Nazis. Terrifying.
