I think even without an awareness of the slavery they are in, though, there are a lot of people divesting for environmental reasons, saving the planet from pollution, etc.
The point of self sufficiency would be survival of the species, as opposed to reliance on food being trucked to you from thousands of miles away, no knowledge of basic survival skills, dependence on gov for energy, water etc. I'm saying that ppl can see the world is f'd. It's a pretty obvious fact at this point, whatever the reasons, divestment is the answer
