The US on the other hand has been politically stable for at least ~150 years and the northeast has been for longer. (Most of my life I've lived in houses that were over a century old. Go to Korea and you will find /no/ living areas built more than 30 years ago.) We're building on one or two century old infrastructure at this point. The two hardest things we have to deal with that no one else does (except China perhaps, but they're not at this stage yet to care, I think) is the size of the country and the age of the current infrastructure.
As a fun fact, some cities in Korea don't even use telephone poles, it's all underground[0]. And I'm sure you've heard of similar infrastructural marvels in Japan.
