I'm not sure if you'll know the answer to this, but what's the best way to make sure sherpas are acceptably paid/to make sure money actually goes to their communities?
Best way would be to put pressure on the government to implement laws and regulations that would require a bulk of Everest money to go towards sustainable local development. And also to put pressure on the businesses that take these climbers on their expeditions and tax them to make sure a good chunk of the portion goes to the Sherpas. The climbers and the visitors themselves have a lot of power since they’re the clients and can use their position of power to influence the expedition companies. It’s easier said than done and given the political situation of Nepal and extreme poverty and disgustingly rampant corruption that’s ubiquitous…. it’s always the common people that suffer. Tourism is vital to the Khumbu region and helps a lot of people lead a decent life, but for the dangerous work that the Sherpas do, they do not get enough recognition or compensation.
Unfortunately, in a country like Nepal, international pressure often is way more effective than national pressure (or at least I feel this way…I might be completely wrong. Feel free to comment on this if I am). So, to make sure Sherpas are treated fairly, the international community and especially the international climber community must do their part and stand up and speak up with the Sherpas and with us, the people of Nepal.
And the most important thing the visitors and tourists that go to Nepal (or any other country) can do: don’t be an ignorant, racist, entitled asshole! Respect the local culture, respect the people, respect the land and their millennial long traditions. If you cannot do these things then don’t travel or if some things offend you or offend your beliefs then politely excuse yourself. Nepali people are very very understanding and respectful of tourists and visitors to Nepal and try their best to make sure your visit is wonderful and comfortable. “Atithi devo bhawa” (roughly: guests are a form of God) is an essential part of our culture. However, if the tourists are being disrespectful and insensitive then the locals do not need to be polite or attend to you. And the insane thing is often the tourism workers and guides continue to serve the clients, swallowing their discomfort without talking back.
