I worked for the state for about 3 years. What I learned during that time is that our government enables people to continue to be dependent on the system, from the welfare system to the unemployment system and everything in between. Instead of teaching people to fish, we give them the fish. I read somewhere that it takes 8,000 sq ft to feed a family of 4. And you could probably feed more if you grow a vertical garden.
Again, it comes down to looking at situations from other points of view. It's easy to cast judgement on people when you don't know them. As you get to know them, it changes your level of understanding. In many cities, very few people have 8,000 sq. feet of growing space, and even more have more than 4 family members.
I do understand that many people are "users" of the system. I'm not discounting that at all. But, I know many, many more who work very, very hard and still not make enough money to make ends meet. Even if we did teach them to garden, they wouldn't have time to do so because they are working long days at their jobs, only to come home and work long evenings to raise their children.
My land is 10,000 sq. feet - and I have a big lot for my city. I have a small house sitting on that lot, 2 sheds, a chicken coop (soon to be 2 coops). I have a play set for my kids to play on and grass for them to run on. I am blessed and fortunate. I do have
some space to convert to edibles. I grow vertically. But I doubt that, no matter how good I get at gardening, that I will be able to feed my family of 5 on my lot.
I don't know about other cities, but in our city, the average sized new lot is 5,000 sq. feet and their huge house takes up most of that space. Those people are blessed by the size of house - but they can't grow squat. And then there are even more people who live in apartments or condos - they can't do much, either.
I have neighbors who don't like that I am tearing out my part of my front yard and most of my side yard for edibles, but again, I am fortunate. I don't live in a neighborhood governed by home owner associations. The worst I'm going to get are quizzical looks, the occasional disapproving comment, glares or stares. I know many people who would get fined if they went against their home owner's associations landscaping regulations.
