Interestingly, it's the same reason why large cartels of several companies, ultimately, are doomed to fail to control the price of their product: In a cartel each member is incentivized to undermine the cartel's price to gain a profit. So usually cartels are effective only for a short time (and, yes, even the oil "cartel").
