Are Hospital Charities a Scam?

I used to donate religiously until I found out the CEO of our local Children's Hospital is making 350k/yr with a huge bonus on top. I think about all those little charities that work for months to collect 25k and they are all so proud to hand it over to the hospital.

Everyone feels so good helping out those poor kids there.

Little do they know, their money went into the pocket of the CEO, probably spent that same evening on some outlandish meal.

Are Cancer charities the same? Does any of it ever get to actually finding a cure? I think charities just keep these places open, nobody is actually trying to find a cure. Milking the people as it were.
