The bipolar superpower dynamic also contributed to greater political authoritarianism in much of the post-colonial Third World. Left-wing nationalist regimes, in the face of Western economic blockades, subversion and outright invasion, adopted garrison state cultures and developed closer ties with the Soviet bloc.
In a sense these were both victories for the United States. The US government arguably has a conscious interest in promoting this kind of authoritarianism. From the standpoint of the American ruling elite, it was far preferable to have the anti-American Third World dominated by authoritarian regimes subject to discipline by the white male three-piece-suited bureaucrats in Moscow (the kind of people Nixon and Kissinger were quite sympatico with), than a liberal anti-American regime providing the demonstration effect of successful economic development outside the global capitalist system.
slam was arguably evolving past its cultural authoritarianism earlier than Christianity. At its height, the medieval Islamic civilization was far more liberal and forward-looking than Christian Europe at the same time.
Communism only lasted 70 years in the first nation to have it, and killed tens of millions with purely man made famines and extreme repression. Libertarianism and its influence on US conservatism takes the greatest share of blame for extreme economic inequality, the Great Recession, and most financial elite crime waves of the past 30 years.
I think the case that I make is that democracy requires capitalism. Capitalism doesn't necessarily require democracy. I've been putting together some data on the top 10 performing non-democratic states in the world and the top 10 democratic states in the world, looking at their growth figures, per capita GDP and other sorts of metrics.
