Yes. The original inference she made, that the chief factor originating from the zip-code selection was the commuting distance put those from outside the close proximity white neighborhood at too steep a disadvantage to overcome. However, we should note that being that the people from these rich suburbs often have wealth to their name, a slue of other issues are observable when comparing them with their lower class competitors.
An example might be the family status of those in these minority rich communities. Lower income neighborhoods often have higher rates of single parents, or parents who can't afford a regular nannie and therefor require tough choices with time. Another might be the fact that their lower income means they might not have a car, or if they do have a car, it is being utilized by their spouse where they can't rely on its availability. Or that due to lack of actual home ownership, drives need to take multiple jobs, or seek income from illegal sources that can cause complications in employment further down the line. Without even needing to request any such info as family status in these resumes, a cacophony of prejudices information can be inferred, just from where they live.
