No, good/responsible breeders DO NOT make money.
Any breeder I would consider personally buying a dog from is probably investing (or losing, if thats how you want to view it) THOUSANDS of dollars per litter. Breeding is also a VERY large time commitment (dedicate most weekends to traveling around the country to show -- also be prepared to spend thousands upon thousands of dollars per year on showing). To be a good breeder, you also need experience with a specific breed and an idea of how you can improve that breed. You need dogs from good stock (again, thousands of dollars). To find "good" dogs you need to spend years attending shows, etc, and learning how to analyze strucutre, temperment, conformation, etc...
Overall, to become a breedr you need to develop a critical eye, develop a critical mind to decide how you want to improve the breed, invest years of your life (all your spare time, weekends, holidays, etc) in getting to know your breed, spend thousands on the dogs that you might want to eventually breed, spend thousands on showing said dogs, spend thousands on vet care for proper testing and THEN breed. Once you breed, be prepared to again spend thousands of dollars on veterinary care for the pups.
Before you think about breeding, why not get some experience. Find a rescue dog, train that dog, put obedience titles on that dog, get to know people in the breed you're interested in through shows, etc.
In the meantime, if you have some extra money lying around, why not invest it in something like a CD so that in 10+ years when you might be ready to start thinking about breeding, you'll have slightly more than you started with?
