I’ve read the whole thing, looking for that sekrit socialism everyone is so sure must be hidden in there, and I just couldn’t find it.

I think the closest brush with “sekrit socialism” is in this sentence:

You’ll need the insights and critical thinking skills you gain in history and social studies to fight poverty and homelessness, crime and discrimination, and make our nation more fair and more free.

Is it necessary to “make our nation more fair”? Only if you think the current economic system is unfair. Some would go as far as to say, “Capitalism’s not natural, it’s not fair and it’s not permanent. It will produce either socialism or barbarism. Which will it be?”
