Not only that, but it is interesting to see the multiplier effect of those overhead funds. If a charity redistributes 90% of donations to their cause, can they raise twice the amount of money by increasing their overhead by 5%? It is well worth it to pay someone a mid 6 figure salary if they are really good at bringing in funds (value) greater than their pay.
If their overhead is reasonable to start with, sure. My personal threshold is 20-ish%. St. Judes and Shriners meet that threshold with their massive TV ad spend. Certain veterans charities have been exceeding 60%. They are money grubbing scum.
