If you are comfortable with all your political, social and cultural assumptions:
DON'T READ THIS BOOK. It's very upsetting.
If you attack people who suggest that the income differential between those who shower before they go to work and those who shower afterwards has increased
enormously in recent decades by accusing them of "class warfare:"
DON'T READ THIS BOOK. You won't like what you find out.
If you think all blue collar working class people are lazy and stupid and worse:
DON'T READ THIS BOOK. If you do you might be shocked.
If you get upset because their are "Reagan Democrats," Limbaugh "dittoheads,"
"Armed Old Testament Evangelicals," and "My Country Right or Wrong Superpatriots."
DON'T READ THIS BOOK. It won't make you happy to find out why.
I liked this book a lot. Of course, the situation has gotten a lot worse since the book was published.
