"It's not that the Left needed to control every piece of terrain in America; instead, they focused on key terrain- and the results, today, are sobering. Avowed Marxist and "founding father" of the Soviet Union Vladimir Lenin gave voice to a key aspect of this strategy in 1922, when he used the term commanding heights in a speech. Following the Russian Revolution, the Soviet economy tanked; Lenin proposed a solution: limited capitalist activities were permitted at the local level, but all the main levers of the national economy would be controlled by the state. In short, Marxists didn't need to control every aspect of the economy; they just needed to maintain a grip on the big and influential industries like steel, manufacturing, and energy. It worked, and the Russian economy temporarily recovered. This military analogy- the "commanding heights"- has captured the imagination of Marxists since, and it was famously dubbed "the road to serfdom" by free-market economists. Conservatives in America spent much of the twentieth century fending off Lenin's economic Marxism. Marx's entire theory was premised on economics and class warfare, and freedom lovers met the Soviet machine head-on- with free-market capitalism and sheer military might. In the end, that combination helped to eventually bring the Soviet Union to its knees. Lenin was an economic Marxist. American progressives are cultural Marxists."
