in the U.S., the income and lifestyle disparity between someone who went to a top-ranked college and someone without formal education might not be noticeable (controlling for cost-of-living), but just from anecdotal evidence, i've heard that in developing countries, there can be orders of magnitude differences ... life in the underclass can be pretty darn crappy. keeping this in mind might help people understand a bit better why youths and adults in these countries obsess so much over their test scores and admissions into universities.
