Ryoko, the whole point of protesting against the cuts is to allow more people, not fewer, to have the choice of going to uni. So to give the unemployed/low paid families/disabled more choice, not less.
A lot of entrepreneurs didn't go to uni. That's true, but maybe they are exceptionally talented or very driven or simply lucky. They are the exception, not the rule - most people can't do it on their own. That's not to say they have to go to uni - but they deserve the choice.
Nurses, doctors, teachers, IT programmers, housing officers - all go to uni. They're all useful.
