It sounds like the issue isn't the wealth favoritism, it's that the colleges all explicitly state that they don't favor applicants due to wealth. The former has always been true on one level: they're expensive. The latter is presumably due to restrictions on various funding systems requiring them to not have any wealth favoritism. If the claims of the suit are true, then it's presumably trying to use proxies for wealth rather than explicitly saying "give us $$$s and we'll let you in"/
