It's not who's paying for the schools. It's who's running them. Unfortunately, the former eventually infects the latter. I suspect that some of the overseas schools you mention have historical curriculums just as tilted as ours, if not more so. Math scores aren't everything in building a robust and creative society.

I put two kids through school, and while they didn't get blasted with propaganda, there were areas of our history that got extremely short shrift. The flag raising picture fell into that category. They were in 10th grade before they got any real detailed modern American history at all. At least in school.

You are wrong on the American medical system, and I have brought the data here several times already. You are welcome to keep believing it, though.
