Powerline has a chart showing the pre-tax operating profit per vehicle for the real Big 3 (Honda, Nissan and Toyota) and the Detroit Big 3. Honda makes about $1500 per vehicle. GM loses almost as much. That $3000 difference is the cost of meeting the retirement and health care entitlements that GM provides UAW workers and retirees. The UAW won those benefits by threatening to strike if the Big 3 did not agree to their terms. The result is that the American auto industry is virtually bankrupt. Something has to give and it will be UAW jobs and benefits.
So, when the union thugs come to your workplace asking you to sign their cards, take a look at what the UAW did to Detroit.
