Those are all great points about how endowments operate, but everyone has the same rules. Your points do not address and they do not explain why UConn is so far behind other Public institutions, that are funded by their states, in far less wealthy states, some with smaller populations. Simply look at the list of Public Institutions that receive state funding. UConn has around half the endowment of the 50th school on the list.Let's just say that you wanted to fund the UCONN Football Coaching Staff as a donor, and let's say as an example that you wanted to set the budget at $5M a year. There are a couple of ways to do it.
1) Donate $5M a year for current use
Expensive but compared to the alternative....
2) Set up an endowment that will fund the $5M/year in perpetuity.
Choosing #2 means you have to donate $117.6M in order to be able to distribute $5M/year at the 4.25% spending rate.
On the field, the results are the same. #1 is invisible to the endowment, #2 makes the endowment look great, but nearly 20% of the endowment would be for a single purpose.
Sorry to beat a dead horse here, but not everyone understands how foundations/endowments work.
If there was some large wealthy donor base out there, it would show up in the endowment. The fact that we are in a wealthy state has not shown up in donations to UConn. For quite some time now, UConn has been pushing donors and yes, donations have gone up, but for people to sit there and somehow think there is some mysterious huge sum of money that we are just not tapping into...well it is the same thinking that basketball is going to get us into the P4/P2.
I do hope that changes in the future, especially as more alumni make more and more money, but the reality is they are not presently out there giving money. Just like us getting into the P4/P2, a lot has to change for the current situation to change in anyway.
