Its percieved as a high price against the average middle income salary., not against how much it actually costs. If you're spending, say, $100.00 a month on gasoline, that is still one of the easier to manage bills in your household budget.
but, The higher that margin expands between how much it costs for a gallon, and how much money a middle income salary pulls in......the worse it'll get for the working class., who then in turn, spend less on consumer goods and entertainment which drives a whole treasure trove of other job markets. The cycle of money to keep our economy going can't be funneled into foreign oil forever, or we're going to get seriously frackstarted as a nation...Just sayin'.
