Clearly you think of "the whole of human history" as what is considered very recent history, that being of the past 50 years. If you look into times before that, you see an entirely different picture.
Also a big no about the whole "where you live" thing. You need to look into different cultures Peter. Have a look at the south American tribes for a start, Plains Indians second, then come back and tell me any of that is "human nature".
Human Nature, like I said, begins and ends with Inquisition and Adaptability.
Everything else is just environmental conditioning, and your specifics are very recent conditioning too. If you look back just 50 years you see a world where thrift was a cherished and highly valued trait. What you're talking about is the past 50 years, nothing more, and coincides with the rise of consumerism. It's not a great leap to see that the rise of consumerism created your "human nature."
