So far this discussion hasn't entirely broached the dramatic rise in material costs along with energy. Manufacturers can't absorb (eat) these increases into infinity, especially in our profit driven, capitolism model. Althought the laws of demand do effect pricing, there is a break point where profitability risk has a drag as well. On another note, there is the issue of a distinct difference in manufacturers being much leaner at this time and the lack of flexibility that portends.
