The goal is not to "get kids to do chores" per se, but to raise adults who are self sufficient and self reliant. "Chores" is a bit of a loaded word because I think a lot of people associate it with dread and a sort of low key undeserved punishment, which is certainly not the goal. In this context it is more akin to having a child pass you pegs while you are trying to hang the washing on the line as opposed to parking them in front of a screen or compete for your attention.
