No they are not, look at the varience in population density of us cities [0] and it's pretty obvious lots of them can expand. The real problem is that jobs are highly local and people want to live in an area where their are lots of job opportunities. Thus, cities with lots of good job opportunities beget more job opportunities like how Amazon chose New York instead of a smaller city.

The lack of societal and governmental support for mass transit makes it doubly difficult for cities to scale.

Gotta support our struggling petroleum industry!

When you build more appartments, more people come to the city. It’s a positive feedback loop. The result is a city with terrible quality of life. The city no one wants to live in. Only then it will stop growing.

Yeah, like Tokyo. It's still one of the most amazing places on the planet, with great culture, ready to get around and even beautiful green spaces. But soon it will continue to grow and become awful...<\s>
