Oh you’re right. Some people should be allowed to hold slaves if it works for them. That’s true freedom and decentralization.

What is a slave? One who is made to work for another under conditions not of his own choosing. And yet you want to impose exactly this on employers - you want to make them provide you with a benefit (paid maternity leave) by threat of force.
No, holding slaves is committing a moral injustice. It has nothing to do with freedom or decentralisation.
