I get the sense I've touched a nerve here. Though I'm not sure where.
I would like to mention I never suggested the frustration comes from workers not being able to own anything at all. Though I still believe what you said about workers not being entitled to the direct consequences of their labor is flawed. Similar to someone saying "I spend all day pulling oil out of the ground, but I'm not allowed to own any of it". That's a fair complaint, and I'd suggest any oil rig worker who wants to get paid in oil should absolutely negotiate for that with their employer. What I was trying to explain is the "direct consequences of their labor" is the compensation they're paid for providing said labor. You, as a worker, sell your labor for a price, same as any other transaction. If you will, your "sprocket" in this situation is the labor you provide.
Our cans of sweet potatoes have an alternate label on the back that says yams, so apparently not much. (This is in the USA)
