Except that much of the Nepalese economy lives off tourism ... so those silly white first worlders that risk their lives climbing those rocks go a long way toward funding the very S&R agencies that exist there (along with helping pay for infrastructure, social services, military, police, etc) so just saying to them "you took the risk, screw you" is a good way to keep other white first worlders from coming there after the mess is cleaned up and thus reducing the quality of life for all Nepalese people.
In the long term, saving climbers on Everest insures more climbers come in the future and leave behind lots of money in a poor poor nation.
