A high education does not guarantee us being elevated up to higher part of the ‘ladder’. But it is true that we cannot ignore the importance of education. In fact, a good education would get us better paying jobs, as many people experience. Class represents power. It includes ‘economic power, and also political and cultural power.’ And obtaining greater power gives us greater wealth. I recommend you to read ‘The Working Class Majority’ by Michael Zweig. It might help you to understand about social classes and social relations.
