Look outside Western culture and watch children, even very small children, as they gather firewood, weed gardens, haul water, tend livestock, care for younger children and run errands. And no one complains because they are mostly outside and usually with other children....And then we think and think about why there's so much obesity.
When we were an agriculturally based nation, American children used to work just as hard and contribute in the same way. But now, Western children are trained intellectually, in school, where they are taught to think about things as the entree to adulthood...
Everyone sits quietly at their desks, thinking and thinking, just when they’d rather be out tending cows or weeding the garden.
Small talks about how young children, working, contribute economically, and notes that we've lost that economic value to children, because we're not farmers. Ah, but confining very young children to classrooms is an economic concept in America. It's childcare, paid for by taxpayers who wouldn't accept paying for the childcare of parents who want (or need) to go to work. The children, unschooled, would be an economic burden on parents who would either purchase private childcare or forgo income from the second of 2 parents working.
If what's really going on is taxpayer-funded childcare, then not only are taxpayers tricked into accepting paying for something they would reject if they knew what it was, but also children are being run through hours and hours of confinement performing exercises that are not honestly premised on benefiting them.
ADDED: There's also that new study that says sitting is as bad as smoking. Since we wouldn't force kids to smoke, why are we forcing them to sit? We're even giving a lot of the kids drugs to overcome their disinclination to sit. It's like forcing kids to smoke and giving them drugs to help them smoke.
