However, not all opinions on the subject among prominent mountaineers are strictly negative. For example, Edmund Hillary, who went on record saying that he has not liked the commercialisation of mountaineering, particularly of Mount Everest and claimed that Having people pay $65,000 and then be led up the mountain by a couple of experienced guides...isn't really mountaineering at all, nevertheless noted that he was pleased by the changes brought to Everest area by Westerners, I don't have any regrets because I worked very hard indeed to improve the condition for the local people. When we first went in there they didn't have any schools, they didn't have any medical facilities, all over the years we have established 27 schools, we have two hospitals and a dozen medical clinics and then we've built bridges over wild mountain rivers and put in fresh water pipelines so in cooperation with the Sherpas we've done a lot to benefit them.
