I make more than minimum wage. But I get your point Jiro. The only "real" problem I see is a lack of available land (community gardens come into play) lack of money (free seeds are available) or lack of time (a family of FOUR!!!)
I learned how to pick vegetables when I was 3 or 4. A family of four can certainly find time to do this.
There was a time before electricity, a time before fast food. How the heck did those poor people survive?
When I was a kid, the old timers all had gardens. They also preserved their own food. No one does that anymore. Well, not with a KFC around the corner.
edit: I can still remember helping my grandmother can food. It was usually when the whole family was together. We all helped out. Shelling butter beans and stuff.
I am assuming people would look at you like your crazy if they saw your family doing this today. It used to be very normal.
