I think the framing in the meme is actually more helpful. Marxists would do well to update their language instead of constantly speaking in terms that sound utterly archaic to modern ears.
I would in fact prefer “Owners vs Workers” because “Laborers” still implies specifically forms of physical labour in a way that makes a lot of people feel excluded from the movement we’re trying to build.
You can still teach people theory. Theory is important. But it makes no sense to open with it. That’s like being asked to teach someone how to use a computer and opening with an explanation of how a CPU works.
No one is going to pay attention to all your theory if they can’t understand how it meaningfully relates to their circumstances.
And, frankly, the term Marxism comes with so much cultural baggage at this point that you’re far better off focusing on what it actually means rather than what it says. You need to get people out of their preconceptions and help people understand what Marx really meant.
