the sherpas don’t just climb everest repeatedly. they climb it repeatedly AND carry all the climbers’ personal shit plus their own shit plus all the basecamp supplies plus they install the ropes and ladders plus sometimes they carry the climbers themselves. all without oxygen.

Many Sherpas have to use oxygen. And those who act as guides are often required to use it even if they have the ability to summit without it. Climbing Everest without oxygen is extremely debilitating even if you are able to do it—which few people can. Someone acting as a paid “guide” for a climbing team could not do the work expected without oxygen. Some expeditions allow some of the Sherpas to make their own summit attempts, in which case they could climb without oxygen if they wanted and were capable.
