Maybe I shouldn't paint all of Europe with the same brush. Although other comments are agreeing with my observation. And I agree that there's plenty to complain about in Europe too, but then still the total costs are often factors lower than in the US. It being outside of my professional field, I've found it quite hard to search the Internet for easily comparable numbers, but what I've been able to find over the years on cost per mile of road, or cost per meter of bridge, I've found sometimes a 10× difference between the US and the Netherlands (where I'm originally from). Maybe I'm confirming my biases, but I just don't think so.
