Traditionally Sherpas only make up a small percentage of "native" workers and they they tend to work in more mountaineering adjacent roles (fixing ropes, etc.) which come with more prestige, money and better equipment donations from privileged clients. Grunt work (porters, cooks, etc) is done by migrants from lowlands, on poor wages, with poor equipment and often effectively at higher risk despite not being involved in, for example, summit pushes. They do not benefit from the biological adaptations, nor noble savage mystique payday.
