"LRTs displace all the poor people"?

I've read a few articles lately claiming that "gentrification" is a term to avoid. Here's one:

It seems like it should be a problem but that article above points to some data which suggests it may not be such a problem. I haven't really thought about it. I could see it being possible, however, that before LRT, people just live far away anyway, and now they have more of an opportunity to live somewhere along the LRT line at least, even if it's not in the center. You hear about poor people and 2+ hour commutes, but this area just isn't big enough for that.
