You say that, but the government is currently engaged in a new reform of the NHS. Having previously pushed decentralisation, competition and increased use and engagement with private providers (Health and Social Care Act 2012 [1]) they are now reversing their position and instead centralising control of everything, abandoning competition, disbanding many of the bodies they created and recreating old ones with new names [2]. This constant churn of politicians with new ideas about how to “fix” the NHS is a big part of why it’s broken.

You should also remember that the British public says they love the NHS but they don’t like paying for it. Current health care funding per capita is well behind other equivalently wealthy nations [3].
