Successful app farms do make a lot of money. Since the development cost of a single app is very low, it doesn't have to bring in much money to become profitable. Produce apps in bulk, and rake in millions. To be clear, my assumption are based on what I read about developer houses like this. Sometimes (though it is rare) their accounts are getting closed on App Store and they hit the news.
