The title explains the premise of he book.
Bad Christians who make a comfortable living should feel guilty for more than just surviving.
It is like when your parents told you to finish your dinner because there are starving people in China. Well the people in China are not starving because you didn't finish your peas. And you know what? If you took your peas and through them out every day for 20 years - God wouldn't care! (Your parents might).
Having wealth is not evil. If you buy a new pair of shoes every month it is not going to take away some African kids lunch because of it.
