I think we need to decide what we want education to be for. Is it to fit people for the workplace, or is it to produce rounded individuals who are able to think critically, understand how society, politics and the media operate and be able to contribute to the cultural life of the UK one way or another? If the former, should employers have to contribute to the cost of getting trained/educated staff? If the latter, should the costs come from general taxation, rather than directly from students?
Do we want to prioritise academic subjects over practical/technical ones, should it be the other way round, or can we work towards a system where people study a mixture, eg classics, maths and health and social studies, with each of those given equal status?
Should schools be places where children learn about things like citizenship, or are taught values that may or may not be those of their parents, or should they concentrate on curriculum subjects and leave parenting to parents? What about religion? Should schools be allowed to embed that into their teaching, or should it be separate, and also left to parents?
Should higher education be available to everyone who can benefit from it? If so, who pays? Should there be repayable fees, and should they be linked to salaries? If so, what about people who get a degree but don't get a taxable job? Would it be fair to expect payback in the form of community service? Should someone earning more pay higher fees to encourage people to take up lower paid professions, or would that discourage effort? If someone doesn't take up a university place and starts work younger, should there be some sort of compensation, such as a more generous tax allowance? Should it be compulsory to stay in education to a higher age than at present, or at least until a certain level of attainment has been reached, whether academically, practically or in some other way that prepares for citizenship?
I think we need to know the answers to questions like these before we can decide on policies and funding.
