This post was conceived to be mainly about British politics, but really applies to conservatism everywhere. In short: America has saved the world.
At a medium length: the explosion of positive, fact-based conservatism that has arisen from America’s classic liberalism has created in the world a widespread revolution in conservative thinking. Conservatism in most places, Britain being my firsthand example, until very recently in history, meant royalism, elitism, and a return to class systems—the latter arising from the others; social mobility was very difficult if not impossible for most.
Then came liberalism, and the American way, and the Great Experiment, and individualism, and self-rule, and the world’s first modern republic arose. There were inalienable rights that were universal for all men (eventually). For a long time, rights were understood to be given to you by the king, or by the law, or by your keepers, but rarely by a creator (take from that what you will, of course). And then over the next two centuries, America, through agriculture and industry, became the greatest nation to have ever existed (in terms of economy, welfare, culture and militaristic benevolence).
Then Marxism gripped the world, or tried to, three or four times (1890s, 1930s, 60s, and now), and anti-historicity became the way of the world; what was old was unjust, and tried, and there must be something better. There was no individual, only community; no individual rights, only the welfare of the society. And this new idea was not conservative. In fact, somehow, it became liberal.
Over the years, then, classic liberalism became known in America as conservatism, and socialism became known as liberalism. American conservatism, in its best incarnations, is still as radical and moral as it was almost two hundred and fifty years ago; perhaps more properly seen as constitutionalism. And this conservatism, perhaps because of its historical context and economic validity, or perhaps because of its compatibility with other historical, economically valid principles: free market capitalism and freedom of the press, has gradually seeped into worldwide culture.
The royalism of old conservatism has receded into arguments about tourism, the elitism has become solidarity, and the class warfare has become class-blindness. At least in the modern strains of conservatism, those newer parties or those smarter leaders, those following the American brand, politics is being saved. My point becomes clear when we compare that to modern liberalism, where there are a number of truths that are not true: all royals are inbred and ancient: evil and corrupt, all elites are right-wing: they control the media, all the upper class are pigs: eat the rich. By these mantras and a few others, socialism is once again rearing its ugly head, but it seems that American values have safeguarded us to some extent, and may still yet save us.
