I'm another who would like to see education free for everyone; but given that fees seem here to stay, I am more concerned about the way the latest proposals are screening out those without GCSEs in English and Maths, even when they want to study entirely different subjects. That seems to discriminate against dyslexics and those with dyscalculia, who wouldn't need either to study many subjects. Obviously, those who want to study Literature or Engineering should be expected to have a basic grounding in one or the other, but why should a talented musician, for instance, (who may have high grades at A level in other subjects) be denied the chance to shine because they didn't pass an exam at the age of 16?
Higher Education is an important source of social mobility, and for a long time there has been a trend for those who benefited from the previous expansion of opportunity (eg free grammar schools and student grants) to cling to their sense of elitism and find ways to disparage the achievements of the next batch of beneficiaries. Simply having a degree is no longer a guarantee of a management or professional role, and I'm far from convinced that it should ever have been. I am a firm believer in education for education's sake, rather than as a passport to a privileged lifestyle, and think that for business and other workplaces to succeed it is important that competition for jobs and promotion should be based on ability rather than the old system which valued qualifications gained at the age of 21 when most of the population were denied to opportunity to study for them. I would rather see those opportunities extended to all, so that we have a genuine meritocracy, rather than a system based on perpetuated privilege.
Pegging the payment of student loans to wages at least means that those who benefit most from education pay back more, and factors in other advantages such as 'old boys' networks and nepotism. If those who continue to earn lower salaries may not pay it all back, at least the educational level of the population is raised, which can only benefit everyone. Keeping the number of graduates deliberately low would mean that fewer people are taught to understand things like how to differentiate between sources of information, how to produce things such as art and literature, and so on. That's why dictators traditionally dislike 'intellectuals' - they are less easy to control.
