Communism, Nazism, Fascism and socialism all gravitate toward bigger and bigger government, because that is the logic of their ideology. Under collectivism, all problems must be solved by the state. The more problems there are, the more powerful the state must become. Once we get on that slippery slope, there is no place to stop until we reach the end of the scale, which is total government. Regardless of what name you give it, regardless of how we re-label it to make it seem new or different, collectivism is totalitarianism.
This leads to the stunning realization that Communism, Fascism, Nazism, Socialism, Neo-Conservatism, Liberalism, The New Deal, Progressiveism, The Great Society, Technocracy, the New World Order, and most of the other political nostrums of our century merely are variants of the same thing. Its name is collectivism.
