First, my local stop n shop sells a loaf of white bread for $1.29 and that's not even a sale price. Second the average income has gone up by more than inflation as well so you would expect the cost of staples to go up accordingly.
my understanding is that other than the top 10% or so, average income is not keeping up with inflation
