Can you imagine the great lengths people would go to to get more money??!
"In 1971, a Philippine government minister (Manuel Elizalde) discovered a small stone age tribe living in isolation on the island of Mindanao. This tribe, called the Tasaday, spoke a strange language, used stone tools, and exhibited other stone-age attributes. Their discovery made television headlines, the cover of National Geographic, and was the subject of a bestselling book. When anthropologists tried to get a better look at the tribe, President Marcos declared the land a reserve and made it off-limits to all visitors.
When Marcos was deposed in 1986, two journalists visited the site and found that the Tasaday in fact lived in houses, traded with the local farmers, wore jeans and t-shirts and spoke a modern local dialect. The Tasadays explained that they had moved in the caves and behaved in a stone-age manner because of pressure from Elizalde. Elizalde had fled the country in 1983 with millions of dollars he had stolen from a foundation set up to protect the Tasaday people."
