why are middle class people committing to ivies + other expensive private schools

its been proven time and time again that the college you go to does not significantly impact your post grad opportunities, at least not enough to justify 300k+ worth of debt. theres only one ivy im applying to since i have family in the area therefore my coa will be in a similar range as if i went to a state school with housing, and even then its HIGHLY unlikely that i decide to commit (if i even get in lmfao). i just want to understand the mindset of committing to that lifelong financial burden
