Wise use of food stamps

One of the things that food stamps can buy you is an orchard!
See, food stamps can be used to buy food, but also food producing plants and seeds! This spring I bought (mostly from Aldi and Walmart) 4 grapevines, 3 blueberry bushes, 2 blackberry bushes, 2 raspberry bushes, a few strawberry plants, and an apple tree. Not all of these are staying at Mom and Dad's house - some of them will be transplanted to the new house. I deliberately bought them with the intent of transplanting since after the wedding I won't have food stamps anymore - I intend to buy and freeze next year's garden seeds too.
Why bother with all this? Well, a $6 blueberry bush might not produce much this year, but next year I'll probably get $20 or more worth of blueberries out of that bush, and the year after, and the year after. It's a literal growth fund. The bigger question is why don't more people with food stamps do this? That's more complicated.
When you have only, say, $200 to spend on food for the month, are you more likely to spend it on food you can eat now or a potential source of food that may or may not grow well for you? Let's say you're a forward thinking individual and carefully invested a few dollars in a food producing plant. Do you rent or own the land around you? Can you put that plant in the ground, or will it remain pot-bound? Granted, there's always the Topsy Turvy (which has added pots designed for peppers and strawberries), but my favorite money-saver food plants are the ones that you don't need to start new every year. (Though I do like peppers!)
It's too bad that the people that would benefit the most from a renewable source of food are the ones least able to plant and enjoy them year after year. I do hope more people at least attempt a container garden - it's so nice to have fresh tomatoes and salad greens.
Maybe a community garden plot supplied by food stamp recipients would be a good idea? Food for thought.
