Me Generation

Us-me - I have to translate this term into Hebrew and I would like to know the excat meaning and usage in American life. The context:
"This narcissistic, us-me culture is slowliy starting to understand that they will have to act as a collective on public health to get the vaccines and trained nurses".
(Maureen Dowd, New York Times
and by saying Midtown New York - is it referred to Manhattan?
My very thanks to you all

Manhattan is an island and comprises one fifth of New York City. It is a boro, with the other boros being Brooklyn, Queens, Staten Island and The Bronx.

People refer to certain areas of Manhattan as being "downtown", "uptown" and "mid-town".

The streets in Manhattan run east and west and are numbererd sequentially from north to south.

So 10th Street is "downtown" while 110th Street is "uptown" and anywhere from the high thirties to the high fifties is called "midtown".

The World Trade Center was located on the island of Manhattan and was way downtown in what is known as the "financial district".

Maybe someone else knows us-me.
I would just be guessing.

I'm not familiar with "us-me," just the "me generation." I am away from my library right now. But I did a search about this chart at members.aol.com/ ENE2020/generations.htm

"Us-me" isn't common; Maureen Dowd may well have made it up. "This narcissistic, us-me culture" suggests a meaning: "this culture in which people care only about themselves and their own group."
