There are many things I would like to reply to this comment but I'll be brief and direct.
If you consider yourself in any way a Marxist or a leftist, you _aren't_, you are pretty far from it. You are not making a rational analysis of society, humanity or reality based on historical materialism. Going back 200-1000 years is not progress. Period.
Clearly, underdeveloped tribes living primitive lives are poor in almost every sense of the word. They may not be poor spiritually, which is debatable, but that's it. There is no colonialism boo-hoo here. Their means, technologies and knowledge are primitive compared to most current day humans. You are romanticizing them based on tedious with current day lives, but if you analyze their situation they _are not_ in a good position compared to humans in more advanced places in the world.
If you think you would like being one of them just think what their average lifespan is, or what their access to drugs, medical treatment, etc is, or what happens to them when there is a drought.
There is nothing to romanticize about it. They have it very rough and they are poor. You shouldn't based your world view on the "noble savage" myth.
