Wow! That’s an interesting thought. Perhaps a massive unintended consequence of airline deregulation was the birth of “fly-over country”. Did that concept even exist before airline routes calcified around a handful of costal markets? China builds high speed rails to cities they want to see prosper and grow. How are we supporting cities like Louisville or Nashville or Tulsa or Omaha or dozens of others? No doubt government funded/regulated transportation systems are a key catalyst in that equation.
