WOW!
I know this is good for the consumer but it is getting at a price that the supply side of the market can ill afford for long. As it approaches and dips below the break even point (~ 50.00 per barrel) it will cost more to get it out of the ground that it can be sold for. This means that companies, who cannot afford to operate at a loss for long, will begin to cut costs with the largest operating costs being personnel.
This has ramifications to those not only directly employed on the producer side but also on the support side as well, (think products and services those employees purchase from fast food to cell phones to Jeep parts). At the pump the break even cost is ~ 2.09/gal on average across the country.
However, S&D dictate local prices so that a 1.99 / gal price in Albuquerque is offset someplace else. Here it's ~ 2.50/gal
