To the degree job growth (and increased car sales that come from more competitive labor costs) is based on two tier-wage structures, how sustainable is the approach? Consider, for example, that Fiat and Chrysler CEO Sergio Marchionne stated that "Long term, (the system) is not available structure. It creates two classes how workers with the plant. It doesn't work in the same direction we are working...to get this organization to work in unison."Why would Mr. Marchionne make this statement? What are the potential drawbacks to materialize?
