I remember a PM, many years ago now, saying the country was becoming 'ungovernable'. (It's so long ago I don't recall which PM, or even which party.)
I suspect this is now true. In part, because human society has evolved to a degree of complexity it's beyond the capacity of our brains to understand, let alone control. I think that's the root of much discontent, as well as facile slogans like 'take back control' which resonated with what many of us feel, given that our world seems inexplicable and chaotic.
I'm not sure any government could resolve this. As it's literally ultra vires - beyond their powers. The laughable idea that putting a demagogue of very limited ability - Farage - into 10 Downing Street would change this is delusional. But in fairness, I'm not sure any human has the ability.
If you think of a medieval village, it's easy to understand how it worked both in political and economic terms. But if you look at modern society, which is now evolving at a faster and faster rate, it's almost impossible to describe how it works. I don't even understand how most people earn a living. The complexity is beyond us.
This alienation from 'the system' has far-reaching consequences. Apathy, anger, frustration, victimisation, isolation to name but a few. It's a perfect recipe for discontent, even without such malign actors as Musk trying to manipulate us.
Anyway, that's my philosophical thought for the week off my chest. Please note I offer no solutions. All I will say is we can't go back to 1955, or whatever year you may think is optimal. Conditions have changed irrevocably.
