@fmf saidI was once told that if everyone paid their taxes fairly and didn’t tolerate or encourage a cash-in-hand approach for work done that there would be enough money to support most of the charities in the UK without including any private donations?
I see it as a good reason to give one's donations to smaller and perhaps more local charities rather than those who might spend too much on 'administering' the donations they get. I don't see how the word "miserly" applies.
