How the heck am I suppose to pay for all this !?

From one year to the next the party with the more dire financial concerns may change: our oldest chose the more expensive school so we had her take out the guaranteed loans. It helped us get through the tight years with multiple kids in private HS and college. If it turns out we have more money later on (via later kids choosing cheaper options or whatever) then we may be able to come back later and help her out with those loans.
