I love how people assume that all the child did was take an extra milk. Guaranteed there is a lot more going on with the child's behavior.
America started losing it's way when they stopped letting teachers smack around their unruly children. The kids face no consequense of significance until things have gotten far past the point they should have, and when they are finally faced with consequense, the public condemns the application of consequense because it seems over the top due to the lack of context.
FRAT version. Beat your kids when they fuck up for a better society.
