       | From the article: As plausible as the cosmopolitan mixing

       | for self-segregation, because they are large enough to enable
       | people to seek out and find others who are similar to themselves
       | 
       | It kind of makes sense that people that earn more or have a
       | higher potential want to mingle with people that are the same.
       | There's no upside for better off individuals to stay in low
       | income neighborhoods.
       | 
       | No matter how much subsidized housing or whatever, low income
       | individuals will be priced out of events or social gatherings.
       | 
       | And the bigger the city, the more opportunities there are, the
       | more segregated economically they tend to be because just a small
       | percentage will "make it". And the rest I think will follow a
       | half Bell curve.

       | As a non-specialist, I think a surprising statement is that in
       | this particular field, there is an expectation that large, dense
       | cities encourage socioeconomic mixing. That seems counter to
       | everyday experience and policies that are sometimes enacted in
       | cities to counter the trend, like bussing kids in poor
       | neighborhoods into richer school districts. The term "ghetto"
       | famously describes an urban trend to cut off poor enclaves,
       | generally with some racial or ethnic component. I guess I felt
       | like it was "common knowledge" that urbanization increased social
       | stratification, whether in ancient times as agricultural
       | societies developed, as I was taught in high school social
       | studies, or in more modern cases where people leave the land to
       | find opportunities, as in Latin America, for instance, where
       | terms like favela are familiar even to English speakers to
       | describe the cut-off, under-serviced and impoverished
       | neighborhoods that have developed. Common knowledge being what it
       | is, that isn't to say that anyone should believe that cities
       | necessarily increase or decrease stratification without making
       | measurements but stories of urban inequality seems to be so
       | prevalent in popular culture that it seems strange that one would
       | state that the opposite is a popular expectation but they have
       | citations so I'm not questioning that the idea is out there, only
       | that it is surprising that it is so prevalent that they need to
       | open their article as though they are bucking a trend in the
       | literature.

         | Urbanization increases social stratification in that the upper

             | This must be why in the 1950's large swathes of Europe saw
             | so many farmers fleeing their land to go live in the city
             | and take up those new fangled factory jobs. Same for

             | 
             | Usually when people talk about "farmers" in the context of
             | social class migrations, they mean subsistence farmers
             | eeking out a living from the land. Not the modern American

               | 
               | Most farmers at the time who owned plots of fertile land
               | would rather break their backs working the land
               | themselves (even if for thin margins of subsistence
               | farming) rather than move to the cities to live in
               | cramped conditions and break their backs working factory
               | jobs for low pay.
               | 
               | The only country folk who migrated to cities to take
               | factory jobs were mostly people who didn't own much land
               | or any at all, making them relatively poor, so a factory
               | job in the city was a better prospect than poverty in the
               | country side working someone else's land. But land owning
               | farmers would never downgrade by going to work factory
               | jobs.

               | Sure? There is nothing about upperclass-hood that implies
               | that it is desirable or infinitely maintainable. In fact,
               | beyond the romanticizing of the upper-class we see in
               | popular culture, I suspect most actually prefer to be
               | working class, especially when coupled with an upper
               | income. There are way fewer nightmares when your only

       | While looking at residential location choice, around 10 years

       | Netflix used to show the most popular movies by zip code, and one
       | side of the boundary it was "Mamma Mia" and the other "Tyler
       | Perry".

         | first was arts/music, second was STEM and honors, and the third
         | was the gym, auto shop, wood shop, and cooking. It's not hard
         | to imagine there were students who never entered building 1.
         | And the only reason I was ever in building 3 was the weight
