That's an interesting idea - though it'd speak really poorly of Spez's qualities as a leader. There's a reason the gas station near has a much higher price over than two decades past while from week to week you'll never see anything more than a 20cent difference and often times see a bit of price lowering to break things up. This may be due to our hunter past or something else but humans are terrible at noticing large gradual changes - but suddenly double the price in front of us and we'll definitely notice.
