With regard to manufacturing, many manufacturing plants already face capacity constraints currently. Adding capacity takes a lot of time. It's complicated by the fact that the low dollar makes importing the kind of equipment required to increase productivity to be more competitive actually more expensive.
Many companies ramped up capacity in the late nineties to take advantage of the low dollar, and then they got burned in 2002. Given that experience, are you still confident that manufacturers will naturally ramp up enough to save the economy in the face of lower oil prices?
