Even technically slavery is illegal, you can still make your kids help you with your cars.
I know slavery was officially abolished back in the 60s sometime, but I discovered a great thing about having kids. You can actually treat your kids like slaves, and not even get in trouble.
I use my kids to help me wash my cars, my truck, and my boat. If I need someone to hand me a wrench in the garage, or to pick up sticks in the yard before I mow, I just make the kids do it. The great part is that if they don't want to do it, you can make them do it anyway because they're your kids. So is slavery really abolished?
Of course I reward them for their help by feeding them and giving them shelter, and paying them like a dollar each to wash my cars.
