oh yeah it gets a bit weird with the grace and joy part calm down you're cleaning a room it's a chore at best.

but it's not automatically wrong for a child to do work it's just that it's a situation primed for taking advantage of.

Also the idea of the protestant work ethic gets a lot of talk about it but it ignores that capitalism developed at the same time and in the same way in Catholic countries and the notion of it being important for people to work hard, be frugal and uphold responsibilities toward society isn't unique to protestantism or a bad thing for someone to believe in. It's when you take the belief that doing those things will make you rich and happy and thus everyone poor is poor by their own fault you get into a dangerous place
