Interestingly, I wonder why this would be a metric of lower quality bread rather than higher? I mean, the obvious way to make the bread last longer would be to pump it full of preservatives, and the white stuff you buy pre-sliced in packs lasts for ages though it is not really bread and the quality is obviously low (or is it? The slices are so smooth, the bubbles so even and the crust not hard at all)
When I have been to France and bought a baguette in the morning, obviously it is normally eaten right away because fresh and delicious, but if you leave it until the afternoon it is already stale and chewy. Does that imply low quality?
(I do buy some food from Aldi, though I prefer my bread from the baker across the road :)
