No, I was saying that if ALDI was competitively selling at $2 a loaf in Cranbourne, under the national pricing system, they would not be selling at $2 across the board. They would be selling at a price closer to $2.50 because otherwise they would lose a dollar of revenue from the Toorak people. That hurts the poor, because they don't experience competitive prices. Such a system also inhibits competition and hence, the efficiency of the market system.
Obviously, this doesn't happen because there would be a huge controversy if ALDI moved their prices up after this (but I wouldn't be surprised if such a bogus claim to "social responsibility" has made before). But what you have to consider is what if the national pricing system wasn't in effect? The prices could be so much more competitive, and they would ultimately help the poor. What I am saying is that so called "fair pricing" is not fair to the poor.
