This is completely incorrect. Infrastructure projects in the US not that big or complex compared to other industrialized nations. The subways in Japan and China make ours look utterly primitive, and ours have nowhere near the scale of those in Asia. However, the costs for building this infrastructure in Japan (where the labor rate is generally on par with the US, if not more) are a fraction of ours. Even better, they have bullet trains, which don't exist at all in America.

This isn't a complexity problem; it's a cultural problem.
