I've finally come to the understanding that when times get tough, people are all for naked power grabs that support "their side", regardless of the broader consequences. You could see it as a flaw in humanity, but I think it's an adaptive trait, ensuring that your tribe secures adequate resources and all that. The real flaw is how we're unable to escape these sorts of evolutionary pressures and replace them with cooperative behavior across tribal boundaries. (In my opinion, this is what will lead us into devastating global resource wars when climate change and peak oil really come home to roost.)
