I don't disagree, but i don't like how you make out socialism as the villain, sounds like you grew up with a lot of cold war propaganda. The absence of socialism means violence and war. If the states had a working social system, crime rates would be much lower.
Personally I like to blame humanism for everything, that is, the delusion that humans are somehow better than what we really are.
I don't disagree that some degree of social policy is needed for a country to be healthy. Brutalism, though, was the blind application of the socialist principles to architecture, which generated more misery than what it tried to prevent.
