Don’t know any threads where schools not being affordable was in the title, but there have been many posters accepted to schools which weren’t affordable, or who dropped schools from the list due to an unaffordable NPC estimate.
Just in this thread, there is one student who was accepted to schools that weren’t affordable, and same for a dad whose D’s friend encountered this situation.
There is a not insignificant proportion of families who can’t afford their family contribution as calculated by colleges, and meet full need schools don’t work for these students. If OP is in that situation best to know that now.
