In reply to j0ntyg:
He won't have pocketed the $30k each, there are the peak fees etc and most of what's left will have gone to the businesses in Nepal which provide the logistics, including paying the sherpas. Whether he's actually lost money will depend on the terms of his contract with the clients - whether they can recover anything will depend on the terms of their insurance.
I fail to see why someone earning more than 5 times the national average wage shouldn't be able to make their own provision for their families in case they are killed or injured. The problem is undoubtedly greater for those sherpas who are not among the elite and who don't get paid such high sums, and greatest of all for the humble porters who get paid very little but may still face risks from weather and altitude.
From what I've read, this is a complex situation where an undoubted tragedy has generated a number of reactions, some of them directly related to the tragedy itself but others may be opportunistic politicking. It looks very messy, and the danger is that it will discourage climbers from attempting Everest from the Nepalese side in future, which will be damaging to their economy.
