Keep these straight
Means of production — the land, water, animals, tools and machines you need in order to produce anything at all.
Relations of production — who controls those means, who does the working, and who ends up with what results. This is what a mode of production actually names.
Usufruct — the right to use land, granted by belonging to a group. It is not ownership: it cannot be sold, and it lapses if you stop using the land or stop belonging.
Karl Polanyi’s three forms of exchange — reciprocity (giving between kin and neighbours), redistribution (everything to a centre, then back out again) and market exchange (price set by supply and demand). Every society uses all three; modes differ in which one carries the weight.
These are types, not stages. It is tempting to read six panels stacked in this order as a staircase, with foragers at the bottom, and every part of that reading is wrong. Foraging peoples are not survivals from an earlier age: Hadza, Ju/'hoansi and Inuit people are contemporaries — citizens of modern states, with wage jobs, schools, land claims and lawyers. Intensive agriculture is not an upgrade on horticulture; it yields more per hectare while yielding less per hour worked, and it arrives with landlords attached. And no society has ever run on a single mode. The words “primitive” and “advanced” do no analytic work here. The three questions on the left do.
