Last week’s announcement that the auto industry could add as many as 167,000 jobs by 2015 merely confirmed what some economists were saying: that lower wages allow car manufacturers to hire more people more profitably. As part of the agreement between the federal government and the unions in 2007, a lower tier of wages was created in order to halt the hemorrhaging of cash the carmakers were experiencing that led to the bailouts. The unions reluctantly agreed to accept the two-tier system, concluding that a lower-paying job was better than none at all. Before the agreement, auto workers were making about $29 an hour, plus benefits (health insurance and a pension plan), which brought the total to $50 an hour or more. The onset of the recession pricked that “high wage bubble” which had been hidden prior to the recession. Under the 2007 agreement, entry-level workers were paid $14 to $16 an hour, plus benefits, bringing their total compensation to about $25 an hour. Although those wages affect only about one in every six workers, it was enough to allow Chrysler to turn a profit last quarter of $212 million, potentially setting the stage for its first profitable year since 2005. At present it takes between 20 and 30 man-hours to produce a new vehicle. Chrysler’s costs are the lowest of the big three automakers, averaging about $1,250 per vehicle. And so the new wage pact agreed to early this fall will add only a few dollars to the overall price of a new car.
