Good stuff, Jim,
Confirms what I've been suspecting all along. The structural problems are not rooted in high labor costs, but in the high costs of the rest of the production system, particularly that of the fixed capital expenditures relating to the hub and spoke system.
It is a pretty typical tendency for the weight of fixed capital to drag an industry (or section of an industry down) while the captains of that industry hoot and holler about high labor costs. More to the point, management traditionally wants labor to subsidize their high nonlabor costs. Traaaaaaaaa....Dition!
In solidarity,
