Mankind was meant to build a civilisation, and to build it well. Going around, scavenging for food, requires a tiny percentage of our intellect.
We're supposed to build, progress, improve and assist.
The amazing thing about humans, is that our natural habitat, can be anything we want it to be. A sprawling city, a tribe in a jungle, deert nomads. Whatever our circumstances, we train ourselves to profit from it. No other life form has any where near that amount of ability.
Surviving, for other creatures requires an upmost effort daily. (except lions, who sleep for 20 hours a day

) But they're an exception because they're royalty.
For the most part, surviving for humans is easy. If our minds constantly instruct us to do something else, then we are meant to do it, we wouldn't have a large brain for no reason.
The vast amount of human beings, inquire about their existance, the state of the universe, why why why. This is our natural state of existance. To enquire. To seek things, to find answers, surviving is easy.
What human civilisation depends on is purely power. Every human has a given amount of energy, or dedication that he/she would want to expend during their lives. Whatever the situation, this energy or dedication has to be spent. Obviously, if you're poor, and living in extreme conditions, this energy would be spent on food, shelter, protection etc.
Now in a wealthy place like Japan, America or Britain. These things are almost a given. A birth right. so a considerably less amount of effort has to be spent on necessities. But the effort has to be spent, so they improve and improve their lifestyles, or alternatively, help others, or both.
But helping others, would take a lot of effort, thereby slowing down personal progress.
This is a very simple concept and i'm probably stating the obvious. But sometimes the obvious seems to be forgotten, and people start having crazy ideas. But materialistic progress is just that, the more material you have and the more greedy you are, the more you make personal progress.
