yeah, as ebola said this is actually a very recent problem. humans have never been known to "hoard resources" up until the last 7,000-10,000 years, which accounts for about 1% of our total existence as a species. humans have the unique property (when compared to other species) to evolve mainly in a cultural way, rather than a biological way. it is *not* human nature to be competitive, destructive, or completely selfish. study tribal cultures (that haven't been wiped out) and look at their approach to property and possessions. they simply have no concept of them. they have complete faith in the "resources" they live within and will almost never store food. they have no need to accumulate possessions because it is seen as a nuisance to them. you could give them a diamond bracelet, they would study it for a couple hours, then through it back into the ground from where it came. when asked about accumulation they would simply respond, "why would we store up food when there will be no problem hunting/gathering it tomorrow?" why they have no concept is a bigger question, but a very important one, and potentially a correct answer to the problems of the culture of "production."
