Administrative staff and sports, I think.

Sport is a recent concept invented by the British idle cast, as a way to spend time and money. The world do not have this luxury right now. We need to spend money on education.
By the way, an analysis of the two longest civilisations (Jewish and Chinese) show that both have been obsessed with education, and both did never have a particularly strong focus on "sports".
Maybe in one century it descendants will count how much of our resources we spent in nothing and will laugh (and cry).

Also given the rising obesity rates and health concerns related to obesity I would say physical fitness is very important in today's society. Education spending should be improved but education isn't all about studying from books. We need mixture of arts, physical education and formal education.
I went to a smaller college that did not have professional teams, and I suspect that students were healthier than at the Big 10 university near my house. The sports were pretty much open to all students.
The captain of my college's football team was a physics major. That tells you something about the quality of the football team, the physics program, or both. ;-)
