About 15% of the American workforce is unionized but over 70% of Mexico's is --- so it can't really be unions per se --- Mexicans love their unions a lot more than we love ours.
Less than 10% of the private sector workforce is unionized.
Okay, I'll have to believe you on those figures. I don't know. But do the unions in Mexico function (or should I say malfunction) like they do here? It would be interesting to know. I cannot believe could possibly be as demanding as they are here.
