Cities like London, Paris, Rome and Berlin have risen, fallen (sometimes several times), and risen again.
New York is just now on a very low point in the changing tides of fortune that come to and depart from every municipality of size and note. Most cities worthy of note sit astride either a port that has means to connect with the interior, or upon a land route that passes through, and that locality has means to provide a rest point and provisions for passing traffic. Cities do not thrive in isolation, and New York City is effectively isolated from much of the rest of the United States.
BS> Take the Southern CA, the LA area...It’s literally been going downhill for 4 decades and the endless line of million of foreign nationals, Muslims and illegal aliens are not going anywhere. In fact they multiply. I could go on for an hour about how that entire region has gone downhill in decline.
Anyone who thinks it’s somehow magically coming back, is seriously delusional.
