One of the biggest rip offs here in the US is United Way. Of every dollar they take in nearly .90 cents goes towards self perpetuation.
The other thing is clothes drives for the needy. Most organizations don't give the clothes you donate to the needy. They either bundle them and sell them for pennies per bundle or sell them at thrift shops. Then they pay everyone who runs the scam. Then they dole out the little bit that's left to the charity.
Moral of the story...if you want to give money to victims, give the money directly to the victims. If I have clothes to donate, I'd rather leave them at a bus stop with directions to whomever finds them to give them to friends who could use them. If they sell them, so what? It's better a poor person gains from my donation than some over paid CEO
I was the UW chairman for my company for two years back in the 90s. What I saw when the UW CEO rolled into town to hand out awards was disgusting. Limousine, private jet, etc. I quit and have never donated another dime to them.
