Into Thin Air

From the text:

Some of the other teams on the mountain that year, failing to understand that Everest was no longer merely a mountain but a commodity as well, were incensed And the greatest hue and cry came from Rob Hall, who was leading a small, impecunious New Zealand team. Hall carped that the Americans were "violating the spirit of the hills" and practicing a shameful form of alpine extortion, but Jim Frush, the unsentimental attorney who was the leader of the American group , remained unmoved.
