For instance, at the University of Wisconsin, there is an VERY large, extremely expensive bureaucracy called DoIT. It stands for "Division of Information Technology". Basically... it is the department for all of the IT people at the University. It is enormously expensive because of the nature of the work they do. And that is just one of the operations level bureaucracies that the University needs. There is Facilities. There is Campus Police, which are very important at a place like UW. Student Housing. Health Services. The list goes on and on.
These sorts of costs are not cheap, but they are necessary. Be that as it may, honest people CAN debate whether or not operational arms like DoIT are functioning as efficiently as they could be. My main point here was only to shed light on operational costs that many universities have which tend to be overlooked in conversations like these. Especially as those expenses are most likely the key contributors to the cost rises being discussed.
