The UAW holds the key to the success of the U.S. auto industry. The recent Senate hearing with the CEOs of the big three car manufacturers was better than most sitcoms. The CEOs were unable to answer questions about how they plan to pay back the loans, or just avoided the question, or how long the loans would keep them afloat, or how they would change their business models to avoid asking the taxpayers to bail them out again. It went on and on.

Executives from Detroit’s “Big Three” auto companies – General Motors Corp. (GM), Ford Motor Co. (F), and Chrysler LLC – yesterday (Tuesday) joined Congressional Democrats on Capitol Hill to make the case for an industry-wide bailout that could spare their troubled companies from totally collapsing. Detroit’s bigwigs have been met with considerable resistance so far, but will continue to make their case today and into the New Year.

This week is shaping up to be another active one on the bailout-and-financing front. First and foremost, Congress returns to work this week to consider a once-unthinkable proposal: Put up billions in taxpayer-backed loans so that Detroit’s “Big Three” can be saved. Expect a fight, however, as the bailout debate finally moves past banks to focus on General Motors Corp. (GM), Ford Motor Co. (F), and Chrysler Corp.

I can’t think of a sector more vulnerable to soaring oil prices than the airlines. Every dollar increase in the price of a barrel of jet fuel adds more than $1.3 million to the daily operating expenses of the U.S. airlines industry.
