An alternative view is that the UK (like the US) is simply a nation in decline, on a trajectory that started at least 70 years ago, and that no matter what policies fiddling with this or that, power and wealth is moving elsewhere in the world anyway.
On that basis, it looks like we're going to have to put up without winter fuel allowances, with ever-increasing potholes in our roads, poor housing, with infrastructure that doesn't work properly, with huge waiting lists on the NHS, and so on.
To my mind, it just comes down to mitigating the effects of decline, and a good start would be to recognise the state we're in and stop making ridiculous mistakes like brexit, which are based largely on nostalgia and national pride and take little account of our reality.
Very pessimistic, I know.
