I will say one thing - the idea that infrastructure is scarce seems falsifiable considering that in major European economies, and overall in the European Union, the level of infrastructure is quite high.

So yes, this might be the case in the US but only due to the unwillingness of the government in the last few decades to collect enough tax in order to fund infrastructure. The current conditions of major European economies prove that no, infrastructure is not particularly scarce if you are willing to fund it.

The US is richer than europe in many ways. It appears to me that its political structure has just decided not to do it. I can't imagine that the relatively poorer countries in Europe (Portugal, Poland) are somehow solving this problem but the US can't.
