Crime doesn't pay

I am a foreigner. Would anyone help me to translate the phrase "Crime doesn't pay"? Naturally, I understand every single word but cannot get the idea.
Thank you

But you wanted to know what it means. It's a slogan from the Department of Wishful THinking. It means that even though committing crimes sounds like a highly rewarding profession, be warned!
