During the last 100 years universities have shifted from training grounds of the ruling class to become significant sites of struggle.
The number of people going to universities has significantly expanded as capitalism requires a highly trained workforce. Many students will go on to work in the public sector or take up jobs in call centres, shops and fast food restaurants.
Students when studying are not part of the working class. They do not have to sell their labour power, face the discipline of the workplace and they have greater time to discuss ideas.
