It certainly shows what happens when human beings are given the freedom of choice, from what they’d like to think and say down to what food the’d like to eat or not. You can never truly know what freedom means until it is taken away from you.
As the Devo song said, however, some people don't want Freedom of Choice, they want "Freedom From Choice."
One of my wife’s cousins grew up in the East - when he graduated from school the kids had only two choices for ‘professions’ that year: Hairdresser or Baker. He refused because he wanted to be a dentist and spent three years in jail at STASI HQ, until he was traded for someone the West had caught. Today, he’s doing well - as a dentist.
