Yes I was earning more per day in 92 than most of the locals would have earned in a year. But I found the locals really friendly. They wanted me to read the once a week Englinsh paper to them so they could learn the language.
The factions were still shooting each other at the time but I never felt in any danger, though some funny stories from that time.
As for the poverty, I guess it's the way it goes. Tourist attractions like Angkor Wat will bring development and money while the rest of the country relies on subsintence farming.
