Lame comparison.
First, racing is advertising, advertising is life blood to a car company. With all the companies talking about performance (new Mustangs, new Challenger, new Camaro, etc.) it makes sense to get into racing. And drag racing is a good buy from a media perspective (read: cheap).
Second, they're out of bankruptcy, are buying back the gov't shares, and are making money. They're "off welfare", they have a real job
Third, you and me racing is just pissing money away. A car company racing is advertising (see above), research and development, good PR, good way to entertain clients, and so on.
Finally, I'm at a loss to see how anyone (really, anyone) talking about doing more anything (hiring, spending, let alone racing) not less, in this economy is anything but a good thing.
