I don't see a problem with groups repeatedly running fund raisers. Sure they can be pests, so can any charity that is seen as always having the hand out, especially if it is for stuff that isn't interesting, but we do have a successful tradition of it here. The R.N.L.I and St John Ambulance are good examples.
As for this; tell their story of survival to get paid mega bucks and not give anything back to the efforts that go on in the background, I'm taking it that the assertion is that it ought to be incumbent on the rescued party to make some sort of donation if they manage to wrangle profit from their ordeal further downstream. I can't get with that for the simple reason parity.
People manage to profit from various apparently harrowing ordeals; write books, sell to newspapers, give TV and radio appearances all sorts of stuff. How many my heart pumps piss interviews have we seen in which a parent has capitalized upon some medical procedure their child underwent, or even in some instances one in which their child has been a victim of crime. Then we have goons such as Terry Waite that against advice go off meddling, get themselves into difficulties and cost my country money, and then spend a bunch of time taking up a bed at Ticehurst that ought to have had a combat PTSD suffer in it that earned their spot. All these and more frequently go on to profit. While all the while all along the chains there are people in the background that may feel undervalued from the low paid triage nurse, the firefighter, the WI volunteers that rattle a box in the hope of a few pence in exchange for their unpaid tea making services, the sleep deprived junior Dr., the mountain rescue bloke, and so on. In short, tough. These people aren't under duress to either do that as their preferred method of getting an income or to donate their free time to it. My standard response would be rather similar to a whinging politician if you can't hack it get the hell out of public life, somebody else can.
To reify a little - A couple of months back not so far from here some bloke was out on one of those surfboard with a parachute attached contraptions, an activity that I consider dangerous. His episode went pear shaped when the wind got up. He got blown up the beach hit a rock and died. Had he lived and gone on to profit from a new book he wrote about the perils of his sport, with anecdotes about that episode, I see no rightful claim from; the lifeboat that attended, the volunteers first on scene on the beach, the paramedic that turned up on a bike, the heli crew that evacuated him, or the medical staff that mended him. I think it would be ludicrous to suppose any of them were entitled to any portion of it. And I think that's at the heart of all this; once a person has assumed a position for a while they tend to exchange gratitude for entitlement. I believe it is known as taking something for granted. It is an insidious rust that must never be pandered to.
