@hawkeye10,
One thing that struck me, reading the article, is that all of these "Foreign Parents are Better" books are sold HERE. The Tiger Mother book isn't a Chinese book, it's an American book. The French Babies are Better book isn't a French book, it's an American book. Etc.
What this says to me is less that Americans are bad (or good) at parenting than that that we're an intensely self-made and self-conscious society.
Compare these books to diet books. French women know how to eat and stay thin. Etc.
Those kinds of things sell here -- and then going ahead and saying "no, American parents aren't terrible for this reason, they're terrible for this OTHER reason" just plays right into the same dynamic.
So, I give a gallic shrug.
