Back then it was "indentured servitude" and after a certain amount of time they were released.
The first US lifelong slave was in 1655. It wasn't until 1720 that it became widespread. So essentially right around the Revolutionary war times.
Pretty sure it was intended to work by draining wallets and getting the mRNA technology approved for future use. We knew from their emails that they knew it didn't work when they released it.
