You also get working class people voting Tory. It's invariably those who choose to punch down, not up.
Once upon a time the cities of Glasgow and Liverpool had many staunch conservative areas. It seems ridiculous now given that I don't think either city has even has a Tory councillor in years. Glasgow has a pro indie majority and even the Liverpool middle class leans socialist.
It was down to anti-irish sectarianism, as the Protestant working class of each city hated the immigrants more than their bosses. It's divide and conquer. There are new integrations of a very old story.
There is a pychological benefit to being better than those beneath you in the cultural hierarchy and sometimes even earning the respect of your masters. Even if it does help preserve the class/gender/race structures that keep the current system intact.
