I think the typical TFA person is earnest about wanting to help poor kids. However, they are not very knowledgeable about what it is that poor kids are dealing with. I don’t mean that they haven’t experienced being a poor kid (though that’s true too). Rather, I mean that they aren’t familiar with the empirical facts about the ways in which material conditions majorly influence educational attainment and life outcomes.
The reason their interest in helping poor kids gets channeled into educational stuff is because the idea that education is the universal solvent of economic problems is the hegemonic ideology of the country. Additionally, the educational story we tell in our society matches what they have personally experienced (as people who’ve excelled academically). By living in this society, they also have probably heard “bad schools” talked about a lot, perhaps by their own parents.
Because they aren’t very knowledgeable, and the hegemonic tendency of the society is to emphasize education, it’s not surprising that the naive college student signs up to be a brave education warrior. It helps also that there is a huge amount of organization that exists to give them the ability to plug in to TFA and other education reform outlets. An earnest, but ignorant, college student who wants to help poor kids can fire off a TFA application on their own campus and get right into the fight (and as Williams shows, feel really good about doing so). Similar outlets don’t really exist for any other kind of cause (there is no Welfare State for America, for instance).
Once the naive college student gets plugged into education reform organization (and especially TFA), they are then path dependent on education reform. Some might defect, but for the most part, there is nothing you will ever be able to do to convince them to decide that they’ve basically been wasting their time. Nothing. They are going to be education/school guys to the very end.
