Their parents abuse them mentally, emotionally and physically, making them angry little beasts. Then they teach them to turn their anger at Jews and Christians.
They teach them that women are dirt and to treat them as dirt, making it impossible for them to have a normal marital relationship.
They make their life on earth hell, and tell them that the only way to be happy is to be a martyr and to get 72 virgins and a dozen young males to play with.
They teach them to memorize their holy book, instead of teaching them to read, write or do math, making it impossible for them to become independent financially.
They teach them hatred for all cultures except their own, making it impossible for them to relate to people from other cultures.
Other than that, they treat them real well.
You have been to the middle east? ;-)
