You seem to be ignoring the real problem of the article, though, which is: how do you do this without further concentrating poor people in poor neighborhoods?
I don't think I am. We should locate some subsidized housing in, for example, the North Loop, Uptown, the Wedge, or heck, even down in Hale by my house.
We do not need more affordable housing in Phillips or Whittier or the North, good transit service or not.
While I think we need more affordable housing everywhere, Phillips/Whittier and North are different cases. North needs transit investment that can help provide economic opportunity to existing communities of color. Phillips/Whittier are going to need to build to stave off the dreaded G word.
