I've been really confused at why cities are becoming exponentially more important rather than less despite better and better remote-working tools and the general de-industrialization of America (reducing the benefits of agglomeration economics). I find the economic claim that a firm being close to other firms being a significant productivity advantage unconvicing. My current theory is after 2008, the suburbs pretty much went belly up. So young people had less money and no desire to get stuck with a dangerous mortgage like their parents. With no desire to own a house or even a car and an emphasis on experiences, people started moving to the cities and the companies followed them there which created a positive feedback loop. So the jobs followed the people, not the other way around. My sense is that there just aren't that many good jobs even in the cities since there isn't any real advantage any more outside some old industrial sectors of being geographically close to others. It's primarily a cultural phenomena not an economic one of the growth of cities. So at what point is the cultural gain no longer rationale and trend flows back to the suburbs?
