The author makes a several interesting points, but then many of his conclusions come out of nowhere. It is certainly of note that lower class children are admonished more than encouraged, it is certainly of note that America and Britain do not have intelligent political discourse.

But where does he justify the anti consumer sentiment thrown in at the end?

And what is the consequence of high SES children being overscheduled? Don't they end up in a higher economic class in the end?

What do the last two sentences even mean?
