Though oil is a primary manufacturing base for chemicals and raw materials, he also cites the author's examples like this-
"Suddenly forced to pay double for a gallon of gas begin to brown-bag their lunches, inching away from restaurants and sandwich shops."
- apparently not seeing the benefits it brings to the brown paper bag industry. So referring back to my point, it is mainly luxuries that will suffer - besides the small detail of fueling our Army, Navy, and Air Force.
I am of the shameless opinion that "luxuries", in 2005, are largely wanton, wasteful, sinful, spiteful, obnoxious, liberal (to be redundant) items that I would gladly see gone from this land.
