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.

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.
