Take Tan Bao, who lived in a pastoral barter system in his homeland in north-western China. Tan's family had the same trade over many generations. Their flock consisted of 63 sheep, 3 horses, 28 geese, 6 ducks.
Tan Bao made $0, yet was able to support his family. Everybody pitched in to subsist.
Now developers bought the land that Tan Bao's family has lived on. Tan Bao & his family are evicted. They move to Xi'an. Now, Tan Bao makes $2 a day working in a shoe factory.
Hooray! Tan Bao is no longer living in extreme poverty. Yet he & his family miss their ancestral homeland & old way of life.
