I guess I would put it this way: The growth of societies needs and wants have far outpaced the capacity to deliver those. Not from a physical resource capacity but from an intellectual one. Combine this with the greed that is part of human nature, these large spikes and collapses will be common place until a new social-economic model is created. One that is a steady state model, which allows for the obsolesce of the antiqued without punishment.
