 how badly things can go, how you need to really avoid making mistakes in order to prevent your civilization from going off course. One of the criticisms or the pushbacks against the Soviet comparison that I hear most often from boomers is the Soviets had to build walls to keep people in, whereas we in the United States, we need to build a wall to keep people out. There are tons and tons of people who want to come here, and that certainly wasn't true of Moscow in 1985.
