I am not sure financial potency is a public university vs private university matter. Universities in general are struggling to keep up with the financial demands and realities of today’s higher education landscape.
Most public flagships receive hundreds of millions of dollars annually from the state. Each $100 million instate funding is the equivalent of $2 billion in private university endowment.
That being said, there is no doubt that states are struggling to provide sufficient funding for their public universities, but many public universities have realized this trend early and have done a good job of developing their endowments. 30 years ago, not a single public university had an endowment among the top 25 nationally. Today, Michigan, Texas, UVa, Texas A&M, Cal and UCLA are along among the 25 wealthiest universities in the country. Michigan, Texas and UVa are three of only 23 universities in the US that have been bestowed Moody’s highest credit rating of Aaa. It should be noted than half the Ivies (Brown, Cornell, Dartmouth and Penn) were all bestowed lower ratings of Aa1.
Ohio State, Penn State-University Park, Pittsburgh, Minnesota-Twin Cities, UNC-Chapel Hill, Wisconsin-Madison, Michigan State, UDub and Purdue are are also in decent shape, with endowments in excess of $2.5 billion each. Today, approximately 40% of the hundred or so universities with endowments over $1 billion are public.
Like I said, in addition to their endowments, those universities receive anywhere from $200-$350 million from the state annually, which is the equivalent of an additional $4-$7 billion worth of endowment.
Also, I am not sure who it is who suggested that private universities have “less oversight”, but that is in fact not accurate. Private universities face their own bureaucratic obstacles and red tape inefficiencies, and from what I have seen, they are not any less crippling or daunting than those faced by public universities.
