I don't have a definitive memory of this by any means, and searching old websites in 2018 is like pulling teeth now that Google "unlaunched" custom date ranges (yet another step on the long journey toward making Google search the pinnacle of vapid "relevance"). However, I seem to remember first seeing it on left-leaning political blogs in the early '00s as mockery of the pattern of complaining about "the gays", "the Jews", "the blacks", etc.. So when pundits complained about welfare, it was paraphrased as ranting about "the poors", when they railed against pensions or Medicare they were angry with "the olds", and so on. It's a very short hop from there to people posting comments that start like "As a poor, [...]".
