Here in the UK, I have to wait about three weeks for a GP appointment. The NHS target for routine appointments with a specialist is 18 weeks, but that target is habitually missed. Routine surgeries are frequently postponed due to a lack of capacity. Many treatments are unavailable due to a lack of funding.
We do spend less than half as much on healthcare per capita than the US and we have better health outcomes by most measures, but it's very much a no-frills system.
It's a tricky issue, the NHS is probably understaffed and underfunded but also extremely expensive already. Massively gutted isn't really true: Spending ( % GDP) has decreased but levels are still at record absolute spending
Nurses are to the UK what Soldiers are to the US, any criticism of the NHS is effectively shot down as Capitalist propaganda. There are some serious questions to be asked about the NHS, which arguably cannot be answered (Even if the result is staying with the status quo) due to an extremely sceptical and anti-capitalist left wing.
