Big food processing firms have been decreasing the quality of food over the years to keep the price low. No more yoghurt but "milk preparations". No more raw milk cheese costly but tasty. Biscuits are getting smaller. Fruits are tasteless and full of pesticides. Let's not even talk about swine, which almost no one knows the real taste anymore since it is produced in industrial facilities and then chemically processed to give it the "standard" tase and color. All of these were not happening on such a large scale 30 or 40 years ago.
My point is that there are other variables to take into account other than prices. Quality is one. You think you have more, but is it of the same quality as before?
