Your link only shows back to 1995, whereas the figures you quoted are about 1901. Even using your link and 1995, milk prices dropped 15% over that period, not 1.1%.
If we look at 1901, milk was around 6 cents per quart according to https://fraser.stlouisfed.org/title/bulletin-united-states-b.... Adjusted for inflation, that's about $2.29/quart today, or $9.16/gallon. That's over twice what I pay and over twice the average according to https://fred.stlouisfed.org/series/APU0000709112.
Yes of course you can buy cheap and bad quality milk but you should strive to buy good product. Same goes for meat. If you do not invest in yourself then you are wasting money
Are you suggesting that milk was higher quality in 1901? I’ve read enough of The Jungle to doubt that greatly.
Well, people say milk used to taste better and forget that getting bacterial infections from milk was very common. Infections from milk and bread were a significant cause of death.
