I have worked at both private and public research institutions and in both cases I witnessed a lot of waste of funding and nothing much of value being produced. I don't know what you could blame this on. I personally like to say it's bad leadership at all levels. I guess, maybe the system is so bureaucratic that the type of leadership you get is the kind that is all talk and no substance.
I have also witnessed a lot of mismanaged oversight: cases where the people overseeing the expenditure of funds were completely unfit to estimate the value of work being produced. Related to this, often time I witnessed instances where people were dealing with bureaucratic procedures so unfit with respect to the task at hand, that they would just sign on the paper, what is effectively a lie. So it's not even that there is a lot of bureaucracy. It's also that a lot of bureaucracy is lies on paper. It does not actually produce any value, track any metric or keep any people in line.
This is only my perception and my experience. But yeah, bad leadership and bad cultural practices that need to be replaced. Unfortunately the people who are to blame are the ones in charge of fixing the problem so nothing will change anytime soon. Maybe this is another problem: bad leadership never gets replaced.
