Unbelievably important: the power of just checking out.

"We political animals often find it difficult to understand that it is a reasonable reaction to tune out and just get on with your life. There are many things you can be rationally ignorant about because you think that your efforts would hardly make a difference. Instead, people go on to work, adapt, and improvise and so, in effect, *continue to improve the world*."

Exit was always more powerful than voice.
