Remember, food is cheap.  It's labor, transportation, marketing, packaging, that make what you eat expensive. Dollar corn in 1950 would be $11.93 today, and it isn't.  
Mom used to pedal eggs for 35¢ dozen in the late 50's and early 60's, those eggs from 1960 would be $3.40 and they aren't either.
My aunt in her later years used to say, "I've got to remember that everything costs 10 times as much as when I was young."  Too often we get caught in the prices of our youth and forget all the government inflation has raised the price of many things.
