Anne Applebaum in The Atlantic:
Unlike Marxism, the Leninist one-party state is not a philosophy. It is a mechanism for holding power. It works because it clearly defines who gets to be the elite—the political elite, the cultural elite, the financial elite. In monarchies such as prerevolutionary France and Russia, the right to rule was granted to the aristocracy, which defined itself by rigid codes of breeding and etiquette. In modern Western democracies, the right to rule is granted, at least in theory, by different forms of competition: campaigning and voting, meritocratic tests that determine access to higher education and the civil service, free markets. Old-fashioned social hierarchies are usually part of the mix, but in modern Britain, America, Germany, France, and until recently Poland, we have assumed that competition is the most just and efficient way to distribute power. The best-run businesses should make the most money. The most appealing and competent politicians should rule. The contests between them should take place on an even playing field, to ensure a fair outcome.
Lenin’s one-party state was based on different values. It overthrew the aristocratic order. But it did not put a competitive model in place. The Bolshevik one-party state was not merely undemocratic; it was also anticompetitive and antimeritocratic. Places in universities, civil-service jobs, and roles in government and industry did not go to the most industrious or the most capable. Instead, they went to the most loyal. People advanced because they were willing to conform to the rules of party membership. Though those rules were different at different times, they were consistent in certain ways. They usually excluded the former ruling elite and their children, as well as suspicious ethnic groups. They favored the children of the working class. Above all, they favored people who loudly professed belief in the creed, who attended party meetings, who participated in public displays of enthusiasm. Unlike an ordinary oligarchy, the one-party state allows for upward mobility: True believers can advance. As Hannah Arendt wrote back in the 1940s, the worst kind of one-party state “invariably replaces all first-rate talents, regardless of their sympathies, with those crackpots and fools whose lack of intelligence and creativity is still the best guarantee of their loyalty.”
Lenin’s one-party system also reflected his disdain for the idea of a neutral state, of apolitical civil servants and an objective media. He wrote that freedom of the press “is a deception.” He mocked freedom of assembly as a “hollow phrase.” As for parliamentary democracy itself, that was no more than “a machine for the suppression of the working class.” In the Bolshevik imagination, the press could be free, and public institutions could be fair, only once they were controlled by the working class—via the party.
