Yeah That's why I didn't agree with that one being sold. But apart from effort, making money is also about knowledge and ability. You can pay someone $50 to adjust your neck the chiropractor, and that process for them is super quick and easy, but they went through serious schooling to ensure they don't break someone's neck. Learning C++ isn't easy for most people, so even one line can deserve SOME money, depending on how you value your work, and everyone is entitled to make money how they want. Just because I wouldn't charge, doesn't mean anyone has to do the same or whatever.
