If that's the case, then your specialized economic role in society is purely as a professional breeder. Other people would need to see that you are contributing your fair share by raising your own family, and be willing to supply you with food, shelter, etc in recognition of this. In fact people generally don't recognize this value. If I thought to myself, "That's a fair division of labor - I'll do the work, and instead of raising my own kids I'll support this guy's family" - my own genes would be removed from the pool pretty quickly (unless group selection pressure were so intense that this was the only way we could out-compete the neighboring villages). On the other hand - if you were willing to raise my kids alongside your own (as a teacher or babysitter), there's a much better chance I'd see that as a fair exchange of value.
