Since being the catalyst and one of the principal organizers of a four day conference, "Towards Self-Sufficiency", on local, regional and world food issues in 1976 (in the Amherst, MA area), I have had an interest in what you are now calling "food security".
In a not-for profit Equity Union financial services system based on principles of mutuality working in concert with ethical, wise, knowledgeable, and intelligent community, inter-community, inter-regional, and worldwide planning would serve the needs of the people.
With respect to the "nature of wealth", I think that the "quality of life" paradigm in lieu of the "standard of living" paradigm needs to be stressed.
"Quality of life" includes personal happiness for self, family, friends, neighbors, and all others. It includes ownership opportunities for all and everybuddy having the things they need, including health, healthy and loving relations with family, friends, neighbors, and all the people of the world. It includes peace on earth, and it includes a future for all the children of the world.
You may be surprised at how many, who are Capitalists, or concur with the apparent success of Capitalism, especially in the USA (I argue that it had more to do with technological "Western Civilization" raping a virgin landscape), would identify with the heritage and tenets of the "Labor Movement" and those of socialism, if the argument is presented to the audience correctly.
What’s the matter with me
I’ve got too much to say
I used to be out there yellin’ at the top of my lungs
and no one was listenin’, anyway
Think I’ll go down by the river, by the highway
Via the busy streets
Where the cars and trucks are rollin’ fast
And say, “do you know how much noise you make
And that we’re runnin’ out of gas”?
Oil junkies, oil junkies
Waitin’ for our next oil change
Yes we’re a thirty weight wonder
Slowly goin’ under
I think it’s time we rearrange
Well, those drillin’ men
Blackening their and our seas and lands
