I dissagree. I know of a number of famillies who used to have a small business, grow their own veggitables, and sell some vegitables on the side. However, the price of food, and the simple services of that these people provided has dropped, due to mass production, and those famillies were forced by lack of money, to change their lifestyles. They had to either sell land or take up a full time job elsewhere which meant that they no longer had time to live the way they used to.
And even if it is caused by choice, I still think that it is better to look at reality than to look at choice. For example, during the totalitarian "comunist" state in the Czech Republic (I live here now) there were many free or low cost oportunities to join youth groups and play sports, go sking ect. and yet people still felt very restricted in their ability to do activities they enjoyed. It was illegal to "gather" in any more than a small number of people, and so planning a hiking trip with your friends could get you a visit from the secret police. Isn't it mearly a matter of choice that many people chose to skirt the law, rather than taking advantage of the many publicly planned youth outings?
The price of food has dropped, but the price of fresh food has risen.
If you live in LA, unless you have the time to go out to one of the farmers markets, its not even possible to buy fresh food. The "fresh" food in the stores isn't fresh. It is usually weeks or even months old. Sometimes it has been on a ship across the ocean stored in a special atmosphere, maybe it "looks fresh" but it isn't. I grew up in Seattle, things are a bit better there, but you still have to drive out of your way to find fresh food. The concept of fresh and the concept of supermarket are just incompatible.
But as you said, fresh food is available in farmer's markets. And if the price of fresh food has risen, it should be possible to make a living growing and selling it.
Except that the majority of people don't seek out fresh food.
It might be possible to make a living growing and selling it, but it is actually quite unrealistic that a sizable portion of the population could choose to start doing so. %100 of the land in the US is owned now. Its not like the fronteir days when anyone who wanted to start a farm could just go out west. If 1 million americans wanted to start a fresh foods farm within driving distance of a city, that wouldn't be possible. The price of land would skyrocket. And that would only be one third of one percent of all Americans. Not even a significant shift. What if 20 or 30 million Americans wanted to make that transition. Is that economically possible in todays world? What if the government were to give anyone who wanted to start a familly farm a million dollars to buy land. Would it be possible then? I don't think so. I think that it isn't about choice. I think that it is litterally impossible for our society to change without the fundamental ideas regarding property rights or urbanization changing.
