I do get incredibly irritated whenthose who for whatever reason do not have children grouse about the public cost of supporting the next generation, as if children are a personal consumer product. Such grousers are classic "free riders" who were happy to take but are unwilling to give.
Oh? I get irritated when people treat children like some type of public commodity for which society in general is responsible. Children are people, and providing for each of them (including their proper education and socialization) is a parental responsibility.
