And with more unions and stronger unions than the US! Some people want to say unionization of some sectors is what makes US construction costs so high, but it really isn't because we can compare to other countries and see that it is possible to do things more cheaply while still maintaining a good level of worker benefits, and perhaps even more worker benefits.
Public construction is more expensive. I think private US construction cost are not nearly as out of alignment with other countries (once past the permitting phase of course).
