Basic sanpro - actually I think PPs suggestion about reusable sanpro being free is a very interesting and sensible suggestion. I don't use reusable sanpro - but if I could get it for free, I would probably switch, or at least at the moment I use a mixture of tampons and pads, and I would probably switch from disposable pads to free reusable ones at least. Interesting idea and made me think a lot, thanks to the person who posted that. And it was interesting about the same idea for nappies too, although I'm more conflicted about that because people do choose to have children whereas obviously menstruating isn't a choice, so I'm not sure how I'd feel about free nappies.
Prescriptions. People saying we should means-test them are talking bollocks lol, it would cost MORE MONEY to provide resources to means-test everybody than it would to provide EVERYONE with free prescriptions. Those figures can be found easily by a quick google. It's why places like Scotland provide them free for everyone because it's CHEAPER to do that than means test (sames goes for lots of other things too btw).
University tuition fees - I'm not sure whether I'd draw the line at one undergrad degree per person or something like that though to stop it spiralling out of control? Debateable. But loads of other countries provide free undergrad degrees, it's hardly a radical idea or anything.
Dental care, eye tests, glasses, and a pair of prescription sunglasses if needed (perhaps opticians could set a level at which this would be necessary? idk). Wearing sunglasses protects your eyes from cataracts which would cost more to treat than to provide people with a cheap pair of prescription sunglasses so again it's counterproductive not to provide them!
School uniform is probs a good idea too. I mean, if you're going to impose a uniform on people, surely it should be paid for rather than forcing poorer families to fork out for it? Or maybe that could be restricted to just families who are eligible for free school meals or the pupil premium or something? Then there would be no need for any extra expensive means-testing.
