At most schools, football and basketball pays the bills for the rest of the athletic department.
In order to balance things out, the low revenue men’s sports get eliminated, while the low revenue women’s sports do not.
No, most school’s sports programs are funded by either the athletes themselves (D2 and D3 tend to be either from the student fees or even directly by the participants themselves) or the school. Only a select few like the SEC and Big Ten football and basketball programs are fully funding the other programs. That’s about 1-2% of the total. The University of Maryland, as an example, was heavily in debt as an athletic program until they joined the Big Ten and Under Armour’s Kevin Planck (as an alum) made a big donation.
