Infrastructure in Paris or Madrid isn't much different than in New York or Boston. And infrastructure in the middle of nowhere Romania isn't that much different than infrastructure in North Dakota.
I've been multiple times to San Francisco and Seattle though, which I still consider to be first-tier US cities and their overall infrastructure* is certainly no match for Western EU's first-tier cities.
IMHO, one area where US infrastructure is markedly superior is the financial infrastructure (availability of capital, legal system) which is on the intangible side of things.
* Roads, Rail, Power Grid, Water Grid, Fiber networks, Public transport, Schools, Hospitals, Police, Fire Departments
Europe's a big place, infrastructure development varies widely. Global top 10 according to the World Bank:
Germany 4.37
Japan 4.25
Sweden 4.24
Netherlands 4.21
Austria 4.18
Singapore 4.06
U. States 4.05
U. Kingdom 4.03
Switzerland 4.02
U.A.E. 4.02
China is #20, just behind Spain. I'd have to average EU, and European data to compare Europe as a whole with China and the US. (But which European nations should I include?)Like if I average the EU28 total I get 3.48 which is just below China and well below the US because there is the infrastructure of Bulgaria and Lithuania (on offence guys!) at the low end and Germany and Sweden at the high end. I am sure the infrastructure of Western China is a night-and-day difference to the coastal South and East. I imagine the US is a lot more uniform.
Here are a few things Hong Kong is superior: Cashless payments, extensive metro/train network, efficient/big airport, high speed internet.
New York is not even as good/efficient as Hong Kong. Now the case can be made that you make more money working in New York than in HK but the comparison is about infrastructure.
The NY subway is one of the shittiest I have tried (and it seems like it breaks often).
Surely a lot of the troubles are Romania’s own fault managing the transition post communism, but I think the interesting part is how does the global market for energy, in this case, decentivize a country to maintain its own infrastructure?
Japan continued its huge infrastructure build postwar but even by the 1970s (Narita airport) it was more difficult.
The next iteration of their high speed rail (SC Maglev) has been in development since the 1970s, with a test track built in 1990. It is under construction now and isn’t planned to be fully operational until 2037.
Compare that with the bullet train, which began development in 1939, construction in the 1950s, and was done in time for the Tokyo Olympics in 1964.
A trackway eats up a massive amount of land and cuts through many different county lines and property boundaries. Even the guy who planned out Market Street in San Francisco had to flee across the Golden Gate on a Ferry once large property owners got wind of his enormous boulevard cutting diagonally across the city.
No matter what you build, or when you build it, people are going to object. I think what changes is the denser your body of law, the easier it is for people to drag projects into the court room, even many different times, for many seemingly legitimate objections. Maybe you don’t stop a project legally, but you halt progress long enough that the costs go up substantially, in a labour market which is already quite expensive and unions fairly common.
If you could easily steamroll any objections, seize the property you want to use without going to court, didn’t have to face environmental concerns, didn’t have to hire unionized labor, and essentially didn’t have to answer to anybody, I imagine the CAHSR would have been built 5 years ago, ahead of time, under budget, and already planning extensions to Redding, Las Vegas and up the Golden Gate Bridge through the Sonoma Valley and up the North Coast with long term (10 year) plans to run a line from San Diego to New Orleans. Alas, we have the Rule of Law, and the Law is very thick.
The cost per km of the proposed California high-speed line is somewhat greater than similar lines in European countries, say, but you'd expect this, because no-one's ever built one in the US before (except for small sections of the Acela one).
