There are cities all across the country that have long since passed their prime. Syracuse, Indianapolis, Detroit, etc. Economic trends shifted, the cities declined. The cities are smaller, poorer, less important.
Seattle, New York, Los Angeles can follow in those footsteps. Port facilities may have lasting value, and the shell of a great city may remain so that the ports can still be used — but most of the people ought to go someplace that isn’t insane. There is nothing for normal people in these blue cities.
Metropolitan areas grew up in specific areas for a reason. Shipping and receiving goods. Industry built along waterway, natural ports, rail hubs and highways. The ports which are automated in most countries no longer need masses of workers. The industries that needed workers in those regions no longer exist or are much smaller. When Blacks from the South flooded the North they were seen as cheap labor, they have since been replaced. We moved to a service industry economy and the cities have become $hit holes. The middle class and above moved to the burbs. Now the burbs are being taken over with low income housing and crap schools. What middle class is left are following the upper class out of the States. Consequently to retain control RAT governments, State, Local and municipal, started giving $hit away creating an entire class of leeches. Very slowly but noticeably the feral entitled class are taking over cities turning them into dung heaps. Eventually you will be left with metropolitan dystopian societies.
