Read "Brave New World" by Aldous Huxley.
Children should not be born. They should be grown. It's so much easier to cultivate a strong economy when you can grow a working class, a literate class, and a leadership class. This is achieved by withholding or increasing oxygen supply to the developing fetus at precisely the right time during the growth cycle. This way you can grow relatively unintelligent people or extraordinarily bright people based on the caste they're grown in.
Then it's merely a case of training and classical conditioning using both vulgar methods as well as some fairly pleasant drugs to motivate your classes to not only do what they're supposed to do but LOVE their role in society. Manual laborers are thrilled that they don't have to deal with the drudgery of having to "think" too much. They just do their job for which they are physically perfect and then they get to go home, drop some great drugs and have lots of consequence free sex. Meanwhile the scientists and politicians are happy as pie that they don't have to do manual labor, and after work they get to go home, drop some great drugs and have lots of consequence free sex.
In many ways it's the perfect society. People are literally grown into the perfect role for their lives. Until you get some fool yahoo who comes in and suggests people should have choice and free will and they should choose they want to love. What kind of a stupid, destructive notion is THAT? Well, you'll have to read the book to see how that works out.
