Yeah, universities spend money on WiFi, technology etc, but I have a hard time believing those are contributing more than a drop in the bucket to what they charge students. I supply bandwidth, WiFi and devices at my home, enough for over 4 people hammering it with multiple devices. If I divide my cost by 4 people over a year, let me tell ya, it ain’t a blip on the radar compared to the $46k ($32k ish in state) annual cost of attendance at UNL.
It it may be an expense for schools that wasn’t there 20-30 years ago, or even 10 years ago, but that isn’t the place to start looking to get costs in line imo. And if a school wants to cut back on amenities like that, large suite style rooms etc., go ahead, there’s nothing stopping them except new student demand and needing to compete with other schools. UNC in my hometown has all that stuff, just as good as UNL does, but cost of attendance there is probably a 1/3 of what it is at UNL. So I don’t believe those are the items driving costs through the roof.
