Should we always assume that the person to initiate a claim is more credible than lower a commenter? I agree armchair conjectures (by me) arent very helpful but it was more my intention to highlight the questionable lack of support for a claim like America doing a poor job educating people.
That claim is not at all questionable!
However even if the US would do a good job, liberal economic professor Robert Reich does present in this course good reasons that the inhomogenity of the results and who profits from what is a problem in its own that ought to be solved in terms of schooling etc.
I hope you are a young person. Over time you will learn that understanding a field takes time and that you need to spend months to get the required minimum knowledge for it. I suggest to you to actually speak with people who work in the field and do research in the field, then you will have done a short cut and can judge whether you want to help fix the problem, the structures or help individuals or if you just wanted to be right online, no matter the real life consequences for people around you.
In any case you are currently lacking the knowledge to differentiate terms, how they are used and how certain numbers are generated. Instead of trying to become an expert I recommend to you again: Speak with the experts, it is a great shortcut.
Besides that you haven’t demonstrated that you are willing to discuss, learn or do your work, which means that you aren’t really a person to be argued with online.
