Adjusted for inflation the average daily wage, for Australians, is less than it was in 1950. However we spend 50 percent less on food than we did then. This is because, in part, then, the cost of food included the care and time invested in family land by small farmers to ensure the continued natural health of that land.
Today farming, packaging and distribution is undertaken by global corporations whose only criteria is the short term bottom line. Market driven economics admits to no ethics, morals or external concerns other than profits.
If you care about the future then buy nothing from any public company!
