Don’t knock them if it works 
Maybe a better question would be if the wing needed more £££ how would you go about raising it? Increase subs, a “wing shop”, run events, sponsored events etc?
At wing level I would expect to see grants and sponsorship from companies.
I’d expect this at some grants at Sqn level too. Shouldn’t it be considered odd that Wing’s don’t appear to do a great deal of fundraising?
Both Sqns and Wgs get moeny from subs but it’s mainly the Sqns that go out to raise extra money. Why shouldn’t a wing do the same? Do they have enough cash?
