"Asian" educational models will never work in the USA. You can't convince middle America to pay more for teachers and/or enroll their kids in programs that involve hard academic work. After school academic programs are crazy, only for obsessed nerds. When would they have time for football practice? This model only works in American communities with large Asian populations. It partially works in low income communities in which the main benefit is keeping the kids away from their screwed up home life.

This is a bit off topic, though. The article is about a guy who makes money off of video lectures. Americans do pay money for videos of things they care about, such as losing weight or improving their golf stroke. Only a small subset of the population would pay for academic tutoring videos.
