We aren't socialists
You are socialists, Social Democracy is socialism, it's just a fucking word. America is socialist too, so is every country in the world that has post, police, fire, military - any services everyone needs that everyone pays for through taxation.
The difference in America is that the capital class has realized that the money generated through taxation looks very nice when it is lining their pockets instead - so they spend untold amounts of money on bribing politicians and generating propaganda designed to convince us that certain things, primarily education and healthcare, are not the same kinds of things as post, police, fire and military.
They have been very successful in convincing a majority of Americans that socializing them would lead to the loss of their money, their freedom and even their lives - even as they take the very same money, freedom and lives for themselves. This is because on the whole Americans are, for a variety of reasons also perpetuated by the capital class, deeply stupid.
