Re: Pleas for extra
"But would someone giving to a charity like the fact that for every £1 they give 30% will go to pay (sometimes huge) wages, 20% to administration, 40% to marketing etc and only 5% to helping the cause itself?"
Sometimes this analysis can be misleading. You need to look at what the charity delivers and how.
I remember reading that the Samaritans had problems because of the amount that was spent on offices and phones which counted as administrative expenditure. But, of course, what Samaitans does is seat volunteers in offices at phones.
A charity that provides medical or social care might spend most of its income on wages because paying those professionals to deliver care is what it's about.
At the very least you'd have to separate out management expenditure.
