I think that there is alot of knee jerk responses to this that aren't justified. Look, UAW adds costs to labor that contributes to production but not all work is union work. But, for US factories, all of the work is still done in the US, and hence, people need/expect to get paid in wages that allow one to earn a living in the US. In general, cost of living, worker expectations, and the labor market yield lower labor costs in Mexico. It is not the unions because many nonunion shops still decide to relocate some aspects of production to Mexico.
I do also think it is important to understand that both union and nonunion shops in the US incur fairly significant costs with respect to health care expenses. I think this is one thing that is vastly underappreciated. European and Asian have employment costs that typically do not include significant health care costs because those costs are off the shops books and on the government provided health care system. You can complain until you are blue in the face about government sponsored healthcare, but for firms located in countries where such care is available (or perhaps not required, I am not sure of the situation in Mexico) this is a significant cost savings.
So, US located shops have several disadvantages that are not due to their tax burden, government regulation, nor union specific demands. One would hope that those cost disadvantages are offset by greater expertise of the workforce, but then that is always an open question in the world that we live in.
