Notwithstanding that what you said seems completely off-topic, I'd have to strongly disagree. In a tribal village of 20, all needs are co-dependent. The individual is dependent on the success of the group and the group depends on each individuals' contribution(s). There is little room for waste and no room for poverty. At the opposite end of the scale we have a nation of, say, 300 million. Large-scale waste becomes acceptable as byproduct of trying to satisfy the demands of the populace and poverty becomes unavoidable to a segment of the population because the size of the group prevents any possibility of equal distribution of resources and opportunity.
