Can be a challenge to neutralize benefits that parents with resources bring to their kids. Often a big reason people have those resources to help their kids.
Something that I expect will make matters worse in terms of affordability of state flagships is fact that increasing numbers of kids from upper income suburbs are choosing state flagships over expensive private colleges. Families either can’t (and no need to get into the age old debate here about whether they should be able to or could have or would have, lack of education priority, should sacrifice for a time, drop down to 2 luxury cars rather than 4 or 5 and 1 luxury trip a year rather than 3, etc. – reality is they do not have full pay liquidity) or won’t pay for full pay private are going to state flagships. Those families are less sensitive to state college prices. As a result, state flagships do not need to be as concerned with other people who struggle to pay increasing cost of state flagships.
