Thank you for a such an smart and insightful comment.

I know that most of reddit users are from USA, so usually i publish some kind of statistical graph with a world ranking where this country doesn't appear very well, i receive picky extra reviews 😅

About teacher ratios and what you commented, i have a question: in USA people has not the possibility to access to a FREE PUBLIC SCHOOL in the ELEMENTARY (PRIMARY) SCHOOL? I would have say yes.

Furthermore, maybe you're also a bit confused regarding for example education on europe: there are too a lot of PRIVATE (paid) educational centers. For example, in Spain there is 32% of schools that are private.

I mention this because the explanation you gave for USA i think that doesn't explain all. Even, let me add this: in the public universities (FREE) in Barcelona (where i studied) there were LESS STUDENTS PER TEACHER than in the private universities (PAID), for the same study course. I can say it because i changed from one to another just in the middle of the course, by money problem.

So, i don't have so clear that paid school means more teachers for same students. There are probably a range of diversity. As you said, it deserves a more deep research. Yeah.

Thanks for be there 😀
