US automakers typically spend more per car on advertising than they spend on labor to build. Labor costs are often under 15% of total cost depending on the model. So even if they paid workers 50% more than today's wages, the cost of the car would "balloon" less than dealer markup. Unions are not making American cars uncompetitive.
