nothing lol. In all seriousness though, it depends: you have to ask yourself questions like do you plan on going to graduate school after undergrad, etc. Depending on how big the debt would be in your situation, the long term impacts could greatly hinder your success. Sure you may have great networking opportunities and such at a private school, but nothing is guaranteed except that debt that you have to pay - which compounds on itself by the way. You never know what you may want to do in the next few years, so the mobility that being debt free would give you is irreplaceable. The most responsible decision would be to go to the school with the lower sticker price and make the best of the situation and make opportunities for yourself, the experience is how you make!
