“Education, education, education,” the mantra of the first Blair government, and one which heralded social change on a scale that has yet to be appreciated. The target of 50 per cent of young adults entering higher education, only recently met, is reshaping the social and the political landscape.
Unlike the social changes of the Thatcher era such as Right to Buy, it was not clear at the time it was announced that getting more young people into higher education would be electorally advantageous for Labour. In the previous election, the Labour Party had been much more successful winning the votes of those without degrees than those who held them. ....
The key to understanding why education is important is political values. Politics has long been thought of as a battle between the left and the right, but this captures only part of the story. There is another dimension of social values, which is not correlated with economic positions, but which includes issues increasingly salient in our politics such as criminal justice, immigration, security and foreign aid.
... On these “social” issues a significant portion of voters who are otherwise on the “left” in terms of economics are in more conservative positions. The core demographic driver on these social issues is education: crudely, those with degrees are less socially conservative than those without.
