Raj Chetty, a Harvard researcher, has done some pretty interesting work that shows that the zip code you are born into can have a huge impact on how much money you earn over the course of your life. Down to the neighborhood level, where you live, the people around you, and the connections you happen to make in life can be major determining factors in what job you take, what college your children attend, and how well off you end up financially speaking. We don’t like to address this very often, but we recognize that it is true, and we have seen increased segregation as we try to separate ourselves from living next to undesirable people and places.
In his book The Complacent Class: The Self-Defeating Quest for the American Dream, Tyler Cowen writes, “in 1970, only about 15 percent of families lived in neighborhoods that were unambiguously affluent or poor. By 2007, 31 percent of American families were living in such neighborhoods.” We are moving in directions where we separate ourselves from people who are not like us in terms of socioeconomic status (SES). Today, relative to 30 to 50 years ago, we are less likely to interact with someone who is very poor if we are rich. We are less likely to know anyone who does not share a generally similar SES, and we are far less likely to have any meaningful interactions with someone from a different SES. Cowen continues, “for where you live, income matters more than ever before, as can be shown by a simple perusal of the apartment ads for most of America’s leading cities.”
This segregation by home value and SES has some obvious consequences, such as schools becoming more segregated by income and race and skyrocketing home prices in some regions of town coupled with deterioration and disinvestment of other regions. However, as the research from Chetty shows, there are other, less obvious consequences from our SES segregation. Where you live influences the opportunities available to you and your children.
We like to think that it is our own effort, talent, and hard work which determines how much money we make and where we end up financially and in terms of the home we are able to buy. Since talent, intelligence, and work ethic are evenly distributed on a genetic level, we would expect that everyone could achieve the same ends regardless of where they happened to be born. Instead, we see huge disparities by zip codes and neighborhoods in terms of ultimate SES. Our segregation is leading to situations where those who are born in wealthy areas are able to make valuable connections, learn the unwritten rules of networking to getting ahead, and receive visible reminders of what can be achieved through hard work and perseverance. Certainly people from the lowest SES background can still network and can still see the benefits of hard work, but research also suggest that when people from the lowest SES don’t have any interactions with people who are economically well off and successful in their careers, they do worse.
Cowen argues that our segregation by SES is making us a less robust society. Partially because we are leaving other people out, but also because it narrows the world for all of us (not just those in low SES neighborhoods) and stymies innovation, development, and progress. We are comfortable in neighborhoods with people who have a similar background and SES to our own, but this does not help us better understand the world, does not help us advocate for and support policy which might help us and others, and does not help us identify and encourage the top talent born in our country. Our complacency as we all search for our own individual American dream is crippling the American dream that we share as a nation by segregating us into complacent bubbles.
