I disagree. I don't see the difference between "the poor" and "people who are poor." As described in the cambridgeblog post, the problem is the underlying issue (e.g., being poor), not necessarily the phrases used to describe the issue. I suppose you can say that, as time progresses, certain terms are saddled with unnecessary pejorative baggage (e.g., "retarded"), so I can understand the desire to swap in a new term that doesn't have the baggage. But sometimes it seems that the difference is so fine (e.g., between "the poor" and "poor people") that I don't have the resolving power to tell the difference.
