I think if you asked these universities they would say that they are taking the very long term view. (For instance the one I went to has been around for 800 years already.) If you are thinking on a timescale of centuries then you want to treat your funds as capital, so you spend your investment income on research, scholarships, building maintenance and other educational goals, but you don't eat into the capital or in 200 years you'll be in a bad place financially. And if your funds are sizeable then investing them and managing them is a big job that you probably don't want to outsource.
