Poor Richard

The problem is that many times there is a cost to not wasting and the owner has no obligation to incur that cost. If you don't finish your lunch because you don't have time and it won't be any good by the time you're hungry again - you probably also don't have the time to take the food and find someone who can use it (in order to avoid waste).

He should only be morally/legally responsible for half the cost of an abortion. There are much worse cases. It's basically correct to say that if you're the biological Father and they know your name you are responsible for supporting the child. Even when the child is the result of a Woman statutorily raping a Male the court has held the Male child responsible for supporting the... child that resulted from the rape.

Those using this standard have to concede that in a society which sanctions abortion the Mother is ultimately the only party involved in willfully bringing an infant into existence. It is her choice alone not to have an abortion. It is this choice (not intercourse itself) which seems to most clearly express the will to become a parent and most directly relates to an acceptance of parental obligation.
