The British NHS should be replaced with a system of national insurance. I’m a staunch labour voter, but the current system is subject to endless tinkering by the party of the day, and it’s broken.
In the UK, the NHS is one of the only institutions that attracts broad unreserved support, though, so this is about as popular as “all college athletes should be locked in churches and those churches should be burned to the ground” would be in the US.
