Totalitarian systems are not more open to ideas. However, when they decide to adopt an idea, there is no debate, it gets adopted with lightening speed.
And that is always an advantage of a dictatorship, things move much more quickly in a dictatorship than they do in a democracy. China was able to adopt one child policy, no way India could have done that.
Anyway, we are going to a party. Bye.
So the only difference in a totalitarian system is that it's faster in making decisions. The US would take longer to scrap user fees as we'd take longer to introduce them because we're democratic. Whereas a dictatorship can bake both ideas more quickly. As for the one-child policy, it would only be a matter of the majority supporting an idea to make it legal. Just consider the attempted cultural genocide of many First Nations in Canada over decades in our history, supported by a democratic majority. A democracy can be just as savage as a dictatorship can be benign. In the end, it merely depends on the government in power.
