I'd like to try to put the matter straight regarding the spending of the large charities. For 20 years, whilst living in Suffolk I was Treasure of a local group of fundraisers for Save the Children. At that time the general idea was that around 10% of funds raised went on overheads. So I looked at the 2019 Annual Report and found the following:
Institutional donors 180,000,000
Individuals and communities 73,000,000
Corporate partnerships &
major donors 34,000,000
Trading 13,000,000
Other _ 7,000,000_
Total -307,000,000_
Fundraising expenses 35,970,000
Charitable activities 270.632,000
The CEO's annual salary is £143,000 and the salaries of the other Executive Department Heads range between £112,000 and £137,000. Compare this with the CEO of M & S, Steve Rowe whose remuneration for 2018/19 was £1,667,000.
Admittedly M & S has a much larger turnover of £10.4 billion and the percentage of turnover paid to their CEO is lower than the percentage paid to the CEO of Save the Children but I don't think that the latter's salary is excessive.
On the subject of small charities, many of which are vanity projects, there is often abuse of funds which you may not be aware of.
