You mustn't forget that universities are only one player of many in the science system. And the main task of some universities rather is education and not research.
There is a lot of funding going to universities, and a lot going to specific projects. I think maybe the main model for research funding generally is that funding doesn’t just appear, people have to go ask for it in the form of a grant proposal. Those grants typically once granted go 40% to the university anyway. Universities, for their part, have been absorbing money for larger and more expensive administrations for the last 30-40 years, and it’s out of hand. Most people I know practicing science feel the opposite of what you said - that less funding should go to the university and more directly toward funding research.
