True. This also explains why nations with too much inland areas: USA, Russia, India, Australia, are inherently and inevitably doomed and uncompetitive for manufacturing.
For the US and the UK, crisis level shortage of truck drivers are not helping things a bit.
In order to move a container inland, you need at least one truck driver, or one person per container.
A 23,000 TEU container ship, can have a crew as low as 20, so let's say if we put it at 23 to be generous, that would be 1 person per 1000 TEU or 1 person per 1000 20' containers or 500 40' containers.
Instead of moving ore, oil or gas across the Asian continent even by rail, to move resources from Russia to China, one can consider developing the Siberian or Northeastern route by ship that takes the carrier through the Bering Straits and into the Arctic ocean.
