Our whole society keeps trying to turn everything into metrics, worshiping the god of data. It is almost meaningless to discuss the value of summer homework if you aren’t going to discuss how children and their parents spend their summers. Our economy, which worships corporations and not humans, does not need all its citizens to be multi-dimensional, well-developed human beings seriously pursuing happiness. Our economy wants mindless wage slaves that pretty much act like cogs in the corporate machinery. Wool-gathering does not benefit the bottom line plus it is time most parents could be putting pins in widgets at the plant. Mindless wage slaves don’t become parents who have fun hanging out with their kids and exploring the world together.
