Basic capitalism, caring only for money, money, money, develops the world very fast, but at desperate cost, because, left to itself, it is as stupid as Trump, producing general poverty to go with individual wealth, constant slumps, colonial and world wars, and. ultimately the destruction of the human world, because it can't think or behave reasonably. As a result, pretty well everywhere it exists, it has been more and more modified by democratic forces, producing, for instance, free education and - in more civilized countries - free health care. the difficulty is, always, that there's a constant tension between such laudable developments and continued private greed, which, as soon as people begin to feel passably comfortable, begin to gnaw away at the foundations of decency to make a slightly larger profit. Social Democratic parties are always at the mercy of these developments, because the rich offer their careerist politicians electoral help if they will sell out those who put them there, with the result that a minority of those will take up some distortion of the ideas of Karl Marx, who pointed out, correctly, that all history is a history of class struggles. Until the species finally get shot of capitalism there is a constant danger that it will destroy us. I think most people understand this, despite all the deliberate muddling of their brains, but find it difficult to know what action to take, a problem which 'common sense' always persuades us to put off until we are dead.
