Like I'm pretty sure the conclusion I had was "oh haha I see your point mr. Vonnegut, too much equality can indeed be a bad thing!"
And I definitely don't remember my teacher suggesting anything about it being viewable as satire of red scare paranoia either
to be clear, I think Vonnegut wrote the whole thing as a joke. I think it is a good short story, in that it's funny, and told in so blunt a manner that a critical reader can't take it at face value.
