Brief considerations on the civilized and the primitive

There are still in the remote areas of Earth a few preindustrial tribal societies who remain stuck in the stone age. What is remarkable is that those people, when in the sufficient proximity of civilization to scrutinize us, manifest neither desire nor intent to possess what we have or live like we live. They prefer to pursue the ways they maintained for millennia. History shows it is only when we force our goods, our poisons (or medicines), our god and our science on them, or when we appropriate the land where they dwell, that they are forced to assimilate, usually with disastrous consequences. What does that tell us about the miracle of industry and the wonders of progress?
