Universal healthcare is one of those things that's not only tricky to set up but also to keep going. Here in the UK, yep the NHS is amazing. But it's also terribly underfunded - despite taking over 10% of GDP (IIRC) we still have long waiting lists, and healthcare staff are overworked and underpaid. Greedy vermin are constantly looking for opportunities to privatise it, the only reason this hasn't already happened is that it would be hugely unpopular. I'm pretty sure almost everyone in the country would prefer more taxes be spent on the NHS and maybe a bit less on, say, fossil fuel subsidies - but here we are. Still, it's one of the few things our country can actually be proud of.
