If the incentives were such that parents wanted to leech off their children, and only have children in the first place in order to create slaves who will do their every bidding, then perhaps. But that's the opposite of how every parent is incentivized, and would effectively destroy the human race in a single generation.

Unless the parent is extremely mentally ill (they do exist), they will always desire to put themselves on the line to ensure a better present and future for their children. They'll let their children feed off of them (which all babies are literally meant to do!), if that's what it takes. They'll devote every hour of every day to their needs, until they gradually become independent.

It's the exact opposite of someone who desires political power over the lives of others.
