this tells me the richest 10% of Americans (the ones who own 2/3rds of the wealth) are white
ehh, this is median, so it's pretty resitant to that, and on top of that, we would not expect the richest 10% of Americans to be equally represented in every category in a way that could skew the figures so much.
on to others:
re: college, yes, college makes a difference, but this is median. while it is certainly possible (maybe probable) that whites are getting more graduate degrees and thus a new class sould be created above "college educated", that doesn't explain why the classes below college educated are so hugely different, either. Plus, studies suggest that black male doctors earn less than their white male counterparts when adjusting for working hours (http://content.healt...t/28/2/557.fulland http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1831663/ from the same authorgroup). (edit: wtf, why is the tinderbox blocking links to the NCBI? haha)
re: single mothers, I haven't seen data that indicates that african american single mothers are spread evenly among education levels - a lot of what I've seen suggests it is far more prevalent among those with less education, so that doesn't make a ton of sense why there'd be such disparity between groups at and above high school educated.
