Pay overseas in those types of jobs is a lot higher, based on cost of living and provided housing... However, the living conditions are typically a little lower...maybe not in amenities, but often in security concerns or government corruption type stuff.
Have you looked in the middle east or thailand? I have a few friends that did that for many years working for the oil companies in American schools. They lived in fenced-in compounds with guard shacks, etc... They ended up making bank in the long run because they essentially lived free over there for 30 years and invested 70% of their pay in the stock market.
