On average? Maybe not. But that is not the point; it's the massive info imbalance between US vs China population
I would bet, of the US 48% who read above a 6th-grade level, at least 2/3 of them know the rate is well over 100%.
The analyst's point is that even the literate in China do NOT know the rates because they have been systematically suppressed by the govt., so the info is simply not available (except to those few who have a reliable hole in the Great Firewall), so the Chinese population is already more controlled.
