Disagree, it's not that simple Billy.
Performing a rescue even from a high camp on Mt. Everest is nearly impossible, and in many cases would probably endanger more people than it would help. Obviously you would have to examine the situation on a case by case basis but as the link shows there have been many instances where a successful rescue is extremely unlikely. Into Thin Air gives a controversial account of some of these instances but there are many more. One of the most central notions of mountaineering is vowing to be responsible for yourself. Realistically climbers that routinely rely on others will eventually die, which is why I don't really believe in most "guided" expeditions. The margin for error is extremely low.
Not saying that I would make the same judgement calls in that situation, but it is very easy to comment on/criticize the actions of high altitude mountaineers from the comfort of your couch. There are often a lot of factors that are difficult to assess and understand given the circumstances. Guided expeditions are often under considerable pressure to summit, given the ridiculously high prices thier clients pay for permits/services, which can lead to bad decision making.
Ed Viesturs' autobiography has some really excellent, valid discussion of this uggly side of mountaineering, if you're interested.
