In the long lead up to Peak Oil, annual increases in the aggregate consumption of oil allowed for ever-greater economies of scale and a declining unit cost.
In this period of abundance, it could be said that wasteful use of oil by over-consumers helped the poor by making petroleum more affordable.
Now that Crude Oil is supply-constrained, the reverse is true. Over-consumers of oil are now contributing to aggregate demand in a way which only ever increases prices.
Suddenly it is no longer valid to say "It's none of your business how much petrol I use as long as I can afford it".
Any consumer of a supply-constrained resource who consumes more than the average, can be said to be disproportionately driving up the price of that resource for everyone else. Discuss.
