What is different now is that more of the crowd can afford to escape...to national parks and the like. In fact, for most of the American landmass (rural areas and small towns) depopulation is the issue. In fact, popular myths like the 'western' aside, the US has always been dominated by its great cities, although over time which cities are the great ones has morphed a bit.

Thomas Jefferson said that the "mobs of the cities add just so much to the support of pure government, as sores do to the strength of the human body." They are inflated tumours growing on an otherwise beautiful nation. Flee to the country.

No. The US population has near doubled - and it has expanded greatly to the West - and now the South even as the Midwest has depleted to some degree. Phoenix and Salt Lake City, for example were still largely open desert and prairie. Now, Phoenix is a megapolis. And SLC's boundary now runs 50 miles north to Ogden.
For a giant humongous change see San Diego and even Seattle. My employment sent me across all these towns and many more thru the '60's. Brother, we are crowded!
Where I live my favorite fishing lake and streams are over run. There is a lake that is a 15 mile hike to get to. Some hiking app turned it into a challenge to post a picture to say you have been there and now it is ruined.
The old days are gone. IT is sad but something new is coming. Perhaps it will be better somehow. I hope that for the next generations. Whatever is coming is coming. Today is a good day, enjoy it the best you can.
