I disagree. American cities before the mid sixties were great places to be

American cities were already in decline but were infused with money for the war effort in World War II. The decline accelerated after the war ended.

These cities peak census year was 1950. Detroit, for example, has a population that's 1/3 of its peak population in 1950.
