I was in Guatemala in 1974-1975, and was not aware of any large influx of foreigners into the Indian towns or villages. I am not saying that it never happened, only that it did not seem to be a common occurrence. Although I met Europeans and North Americans who were living in Guatemala City, I saw none in Totonicapan other than a few Catholic priests.
In short, the parallel you draw between Guatemala and Israel seems tenuous at best.
Did you visit Lake Atitlan? I sat on its shores one afternoon as a priest explained it all to me. I also spent a lot of time visiting mountainous Indian villages - where I saw no foreigners - and a factory town ( one of the -tenangos) where I couldn't help contrasting the downtrodden appearance of the Indians with what I'd observed in the mountains.
