I think you must have little to no experience in the non-profit world? Pretty much every foundation has an annual "gala" of some sort, from the local Ducks Unlimited oyster roast and awards ceremony to the Gates Foundation annual gala which is very similar to the Clinton Foundation's. In fact I just helped out in putting one on last week (closer to the local Ducks Unlimited than the Clinton Foundation), and it raised a good bit of money and visibility for the organization. You may want to actually participate in the world of non-profits before pontificating on them, lest you sound ignorant.
Do they spend 60% of their donations on their annual gala?
I'd assume a gala is really a fundraiser? So if they are losing money that would be odd.
