As much as I think unions are an absurd way to deal with income inequality by doing everything terribly and expensively, this is a really unsatisfying answer when it comes to explaining why the US is so bad at infra construction. Freaking Germany and France are hardly famous union-busters, and somehow they manage to be infinitely more efficient than us at public works projects. There's clearly something more complicated going on than "Unions."

Care to elaborate?
