What do you meant as far as discrimination v. discrepancy? Just because numbers don't line up doesn't automatically mean there is nefarious intent. Corporations can care only about profit and still operate within the bounds of the law.
thats what I'm saying. many people jump to 'discrimination' when its merely a discrepancy. discrepancies exist everywhere for entirely benign reasons. furthermore, believing its discrimination for its own sake (like age discrimination) would contradict the belief that companies optimize for profit (which I don't think is a bad thing) since there no absolute causality there.
