Here's the reality. My uncle taught at Thomas Jefferson High School in Brooklyn in the 90s. He had a class section with 90 students, which sounds crazy except that he met 30 and regularly saw 9.

One kid was selling crack. Another held him at knifepoint over a Twinkie. The rest were either there for lunch or just trying to scrape by, living in terror.

Those kids sent going to function at MIT.
