We need to recognise the difference between the GP rant and what you're describing. The austerity is undeniably still reverberating through the country. It will take years for this ship to turn around, although it is being turned around. For example, in just about a month we're getting European-style rents with the Renter's Rights Act, which is transformational. We can and should do better, and everyone can contribute to solving those issues, but after a decade of nothing the necessary changes are finally being implemented.

But the rant is entirely counterfactual. Britain is a very rich country with beautiful and recovering nature, a healthy and educated population, one of the more capable armies in Europe, a functioning deterrent, and a relatively healthy political system. We just got two new parties becoming credible threats to the "main" two (regardless of the parties' views, the political competition itself is a much healthier situation than the American duopoly)! We just abolished hereditary peers, which is a constitutional change (and it can just be done)! Below the everyday media noise, we're doing alright as a democracy.
