I find it very illuminating whenever internal TFA alumni mailings find their way onto the web, like this example over at Gotham Schools. I don't think I know anyone who has been in TFA. There is no shortage of elementary school or humanities teachers in any state I've lived in.
Anyhow, I don't need to pick this apart in detail, if you read the email you'll probably either say, "These people are really weird," or "I don't see anything wrong with that."
The most obvious omission to me is that in a time of budget cuts to schools, it does not seem that the "stewards of educational equity" are supposed to advocate against cuts to urban schools. That would be the wrong kind of activism and the wrong kind of equity.
How much of this is a generational thing? I think this movement is beginning to suffer from too much insularity, too much talking to itself, making arguments that don't make any sense to people outside the corps.
