I visited Angkor Wat and Angkor Tom in Cambodia recently with my husband, Philip Anasovich. We had an excellent guide, Seng Kompheak, an archaeologist who's worked on these and many other sites. He said that at the time these temples were built, 9th - 13th century, taxes were important; wealthy people paid them, if you didn't have the money you would work on building temples. I gave Kompheak a copy of 'Jaya.' The huge low reliefs illustrating religious and political scenes at both temples are masterpieces.
