Unfortunately, this isn't true. In many non-privileged areas you may have supermarkets like c-town, associated, fine-fare, or other non-boutique supermarkets that mostly stock mainstream products from mainstream food producers, as such they usually have very limited selections of organic and non-GMO foods, if any. So unless rules like these are passed, those groups are reliant on companies changing their behaviors based on market trends (such as rice krispy treats removing high fructose corn syrup from their boxed product). Worse, even in those cases most large food producers tend to roll out the "healthier" products specifically to the privileged areas, leaving the non-privileged with "worse" product.
