What a ridiculous aibu!
I have worked for a DEC charity. I now work for one that provides a service that the govt should be providing, but farms out (I don't think this is always possible though as a pp said). I have also worked as an auditor and in the commercial sector. I could add at least 40% to my salary if I went back to practice or commerce. I don't because I believe charities are important and I also love what I do.
All charities are audited at least as rigorously as a company. I'll add Housing Corporation as another regulatory body to the lists earlier. Large charities are also likely to have to report under International Standards soon as well.
There are of course some people who abuse the charity system/status but you sadly always get people like this everywhere. The vast majority are doing an amazing job with serious challenges and less reward.
It's gratifying to see so many mners so clued up. I saw the op and was expecting another uninformed bashing
