There's plenty of historical evidence to show that the NHS in general flourishes under Labour governments and struggles under the Tories - eg public approval, waiting lists, A&E response times. That tends to be linked to funding. All governments increase NHS budgets, but Labour have historically done it by more.
However, as ever with the NHS, it's complicated. The NHS is horribly inefficient (I know, I've worked in it) - and we have to cut the current regime some slack because of Covid. Demand has increased, waiting lists naturally lengthened while the NHS was dealing with the pandemic, and NHS productivity has failed to improve even though funding and staffing have increased significantly since 2020.
The NHS is hidebound by the tension between its leadership and politicians, it's too big and too complex. The fact that it's free at the point of delivery means that people abuse it. The population is ageing and we're generally getting unhealthier. We need a national conversation about what our health service does and doesn't do. We have 4 choices:
1. The NHS limps along unchanged, without the funding it needs. It will slowly die, with crumbling facilities, worsening access and increasingly unsafe services.
2. Keep the current NHS remit and fund it properly. That will bankrupt the country by 2070, maybe sooner.
3. Shift to a funding mix split between taxation and private insurance (like Germany and France). This would give the NHS long term viability but we'd all have to pay more.
4. The NHS shrinks (eg only providing long-term and emergency care), with us individually having to pay for non-urgent stuff like GP appointments and hip replacements.
All 4 options are electoral suicide, which is why politicians shy away from a proper debate about the future of the NHS. But sooner or later we're going to have to grasp the nettle. Until then, the only solution is to try and improve the NHS's appalling productivity record. Fair play to Wes Streeting and Labour for talking about this openly. It may not be popular, but it's the right thing to do.
Here endeth the lesson!
