And that system used to work because people used to spend a higher proportion of their incomes than they do now.
Well yes, and apparently most customers didn't think spending so much of their income on food was as wonderful as you do. It's very unlikely that grocery stores are involved in a huge conspiracy to force everyone to eat worse food. They'd probably much prefer to sell higher-quality higher-margin products because they'd earn more profits; Whole Foods does exactly that. But amazingly it turns out that different people have different price/quality tradeoffs, and I don't see how any of them are objectively wrong.
And what will they stock up on? Processed foods that have long shelf lives
And they shouldn't have that choice?
You're missing the point because you do not accept that foodstuffs are *TOO* cheap, that's the problem.
Right. And I'm sure that if the stores raised their prices to the "proper" level, you would not at all be complaining about price gouging and how the poor can't afford to feed themselves.
Go and ask the poor sap on the DVD counter to recommend you a good family movie for the evening.
And I take it Netflix is the devil incarnate.
