Businesses have always done this, do you think Sears and Monkey Ward spent a fortune printing and mailing all those catalogs so your outhouse wouldn't run out of paper?
When I was a kid, I frequently suggested that my parents could make me very happy, buying me stuff in the prominent store checkout displays, or "As Seen on TV". I really don't know if it would have made me happy, but apparently it made them happy to ignore my suggestions.
Now Mom's in an $11,000 a month nursing home, so I guess I got over it.
Edit; One nasty, greasy, salty, fast food orgasm a week is hardly going to ruin the health of a kid eating good shit at home. The real problem is kids and mothers have to much free time to get in trouble. If mom was churning butter and beating the laundry on rocks, while the the kids were sorting clinkers from coal down by the tracks, this wouldn't be an issue.
