Cambodia was heart breaking for me; even though it has been years since the genocide has stopped, the poverty is so vast, and sadness and fear in people's faces has not vanished. They are the most gentle people I have met. Unfortunately, Vietnam's government has still so much power over the country, that can you imagine all of the fees to see Angkor Wat (45usd per person, and there are millions going to see it) end up in Vietnam's hands instead of helping the country recover. Not sure what the people there are doing or even can do, but personally when I visit such places, I try to pay for services directly to local people. For example, we were in Angkor Wat for 3 days and we hired a personal local guide to tell us all about the temple, the history, the people. He is the one that told us about all the fees going to Vietnam. Normally we never hire guides, but in this case we thought we could help a little. Did the same in Nepal and Egypt Seeing that the money stays in the country and with a company that hires locally and treats its emplyees well.
