My dude it’s typically called service learning and your pessimistic and overly pedantic take on it isn’t great.

The notion of these activities is to get kids out in the world to see how it works and interact with its systems AND possibly have them help out and learn about things.

When I was in school I did my service learning with a nature conservancy near me, it was fun and was treated like a school assignment.

They’re not slaves and your comparison is wild for anyone living in any form of servitude.
