This sounds like "world ends, poor people hardest hit". Of course, any price increase would affect poor people, but that's not how "discrimination" works - you can't just claim that anything that increases the price of any good is "discriminatory" (otherwise we couldn't have most of regulations, since many of them do increase costs, whatever are their other perceived or real benefits). And, "poor people" are not enumerated there anyway - it's "on the basis of race, color, religion, national origin, or sex". You could of course claim that since there's more poor people among, say, blacks than whites, it's related to race, but that would extend "discrimination" way beyond point of any usability - you could then claim that producing and selling any expensive good is racist, which is insane.
