In Europe, at least, the post-war prosperity was based around at least some acknowledgement of the mutual dependency of citizens. Democratic socialists co-existed with the centre-right, nuanced, but fundamentally in agreement that a functioning society requires obligations as well as entitlements. The construction of a social stability based around this assumption marginalised the most extreme while creating conditions which, in retrospect, look idyllic.
The real enemies of the people are not the political poltroons, such as Trump and Farage, who exploit their self-styled iconoclasm, but those who seek to impose a political and economic hegemony based around exploitation of others - be they in the same room, or halfway across the world. In reducing the human to the status of a parasitic organism that eats into the pursuit of profit, they have paved the way both for inchoate resentment and for the destruction of the social capital that could have acted as a brake on fascism. In electing the fascist, and doing their bidding, the howls of self-destructive rage are misdirected and the reckoning will not be pretty.
Any belief in progress is now on hold - the inability to organise and mobilise caused by the tendency to prevaricate and make much of small differences rather than focusing on the enemy is the blocker. Turning on each other is less frightening than taking the battle to the enemies of the human race and the vermin who cheer them on. This is a descent, not just to the 19th century, but to the Dark Ages. Pessimism is the watchword, alongside a recognition that there is nothing else to do but ensure that those who share values and aspirations are recognised, protected and supported. In the meantime, the lunatics have taken over the citadel and have merged with the idiot barbarians. Depressing times.
