I agree with you! It seems that if you criticise the NHS, and think it needs "dismantling", supporters only have, well private's no better, to throw at you.
My local NHS Trust isn't fit for purpose. It's an absolute shambles throughout, well-known scandals, and the quality of care my mum received recently was utterly appalling, and this was from nurses and hca staff on the ward. They are an absolute disgrace.
The NHS is a mess, and throwing money at it without going right back to basics is a complete waste of money. In an ideal world it would be stripped back, and the whole thing built up again from scratch, but it's people's lives so it's incredibly difficult to do that.
Do I think private is the answer, no I do not. The NHS is already insurance based, through NI, and that needs to be ringfenced, recalculated, and be made clear that we're all already paying into the scheme because right now a lot of people are invested in pushing the narrative that it's not being paid for by the general public, when it is.
I don't know what the answer is, but investment without structural change isn't going to work long term imo.
