UNCW is trapped in the government UNC system, and therefore cannot expand as it wishes, whereas Campbell is a private school and has no limitations. It's the reason Campbell has a law school as well as a pharmacy school, and UNCW has been limited to Marine Biology, Nursing and Education degrees, with a decent business school.
Along with the ability to offer any degrees it desires, Campbell ends up with a wealthy donor base, high tuition and fees, and the ability to build any facilities it can get a loan for. Educate yourself a bit before spewing your ignorance.
