Tokyo has a population of some 14 million. Dallas is about 1.3 million. Did you pick cities with populations exactly 10x apart on purpose or something?

Got any real stats?

So what? Why do you need one city with 13 million people when the US has the land area to build 10 cities with 1.3 million people?

Because that's where people individually want to live. Cities are getting bigger, rural areas and small towns are depopulating.
