Let’s cut the BS. Every American city,let alone most liberal run jurisdictions are complete sh*tholes. What are going to do about it? The answer is nothing.
You are correct. The problem is that much of America’s infrastructure was put down by the 60s and has been neglected since then.
When I compare JFK, Newark or Chicago or Atlanta with Dubai, HK, Singapore or even Frankfurt or Paris, the American airports are way, wayyyy behind — even behind Mumbai and Delhi (notable exception being Cincinnati)
