Some top Wisconsin university officials fear that if UW-Madison splits from the rest of the University of Wisconsin System it will result in unnecessary duplications, competition for limited resources and skyrocketing tuition. Those were some of the circumstances that led state university campuses to merge 40 years ago, creating the UW System. Now, with a proposal to separate the flagship university from the rest of the fleet, some leaders are concerned Wisconsin will return to what they see as the bad old days.
