Covid has had a real long term effect on physical and mental health
Obviously we have, we have just been through a pandemic
I do not know about that, but our reaction to the pandemic left us more vulnerable
I'm certainly not going to argue most of the points you've made, as I mostly agree, but for info of how the UK has differed post-Covid, here's some stats from an IFS report.

For me, this one is equally important, as it shows the huge regional variations in health-related benefits. There are obviously complex relationships between poverty and health, but in my view, this is exactly what Labour should be targeting.
It's partly a sign of just how awful the debate around politics is these days (and that's not directed at you - I find your comments educated and interesting), where the media, and social media force everything to the extremes. Most (certainly on the left), would agree that it's a terrible indictment of our society, yet instead of debate around why this happens, and what we can do change it, we end up with a "Tory cunts" v "Lazy Scroungers" and very little in between.
