Before we get in to any discussion about optimal classroom sized we have to remember one very basic thing: all science is bullshit. Science is just a tool that differing ideologues use to compete with each other. There are scientific studies showing that small classroom sizes are optimal and there are scientific studies showing that large classroom sizes are optimal. Both are equally worthless. They have been made up. It's just common sense that a larger classroom size is going to be more optimal than a small one. By "large" I am referring to a crowd of at least 10,000 people. 100,000-1,000,000 people should be the optimal classroom size. This is simply because any effort to teach 10,000 minds is going to have to be an honest effort. There can be no wishy-washy teaching in that environment. It's got to be macro-oriented; bold, basic, pure. None of that detail shit. And the kids are not going to socialize with each other because there is no medium upon which their egos can rest. They are going to be drowning in a sea of unidentifiable human shit. They'll never see the same person twice. In order to achieve this, rural school should be shut down and the teachers laid off. All humans not living in major cities will be forced to relocate. There will only be a handful major human population centers in the USA (LA, Seattle, Chicago, Houston, New York City, etc.) There will be fewer than fifteen teachers in the entire country. All of the country's children in these cities will attend one "school" (a large square). There will be no tests, no books, you just show up and listen. Once you know how to speak English you are educated. This is all that is necessary for a functioning and efficient civilization."
