Ah, as a kid/teenager I picked strawberries a whole summer holiday to earn the cash for a C64. Back breaking stuff but the reward made it all so worth it!
There's something to be said for a physical, temporal cost to receive a reward. Cooking my own food or chopping my own wood for warmth really makes me value the result that much more.
Although I don't know that this sentiment applies to this article since it about industrial farming, and not personal gardens.
