I tried to teach my oldest (6) to do the laundry, including things like putting it in and switching it to the dryer. Unfortunately, the washer is just too deep for her to effectively reach the clothes. I *could* have her put stuff in the washer and get stuff out of the dryer. But it's also hard for her to carry a full load up the basement stairs. So right now I just have her fold loads of kid stuff and carry it in a small, kid-sized laundry basket, up the stairs by person. She still puts stuff in the wrong people's drawers *all* the time, though, drives me crazy. But yeah, she's 6. By the time she's 18, I would *hope* we'd have all these things ironed out.
It does seem like people want children to be less independent nowadays, though. Our local children's agency recommends that children not be out of line of sight, including in their own backyard, until they're 8 years old.
