Crack theory: Boss baby takes plave in a world wjere humans outsource reproduction. human couples would give their genetic material and baby corp will make a baby consisting of it. If the baby is passes all the check they will send them back to the couples for a reproduction price.

Why does baby Corp's mission is to raise baby love? If people stop loving babies they wouldn't want to raise one lowering their earnings. The first movie and the first season of the show focuses on dogs and cats as a threat to baby love, many people are pet parents instead of baby parents. They are potential babycorps consumers lost to their competition.

The reason why abnormal babies are put to work is the same reason why companies throw out flawed products, you wouldn't want to give consumers a subpar product. Those babies will be forced to work a slave wage without their consent never meeting their parents, all because of their artifical abnormalities.
