Another important thing to note in this conversation is that the 70s were a hard time for a lot of US cities. So even though NYC was in a rough spot, it's not like DC, Philly, or Boston were much better. Being on the East Coast and the eastern time zone is critical for a lot of business, so it's unlikely that Chicago or LA or SF could have just taken New York's corporations, should they have decided to start jumping ship.
