A forum I used to post at was Prog dominated, one of the posters had run a community garden in one of those Blue Hive utopias and as he described it it was basically white slaves so the people of color could stand there and demand free veggies.
Our church has a community / food bank garden. About 70-80% is given to the food bank, the rest taken by volunteers as payment unless used by the church in preparing communal meals.
All the volunteers are white, mostly retirees. Most of the recipients are Hispanic and black. And we live in a barely majority white area.
