On May 5th, 1818, Karl Marx, hero of the international proletatiat, was born. His revolution of Socialist theory reverberates throughout the world carries on to this day, in increasing magnitude. Every passing day, he is vindicated. His analysis of Capitalism, development of the theory of Scientific Socialism, and advancements on dialectics to become Dialectical Materialism, have all played a key role in the past century, and have remained ever-more relevant throughout.
He didn't always rock his famous beard, when he was younger he was clean shaven!

Some significant works:
Economic & Philosophic Manuscripts of 1844
The Eighteenth Brumaire of Louis Bonaparte
The Civil War in France
Wage Labor & Capital
Wages, Price, and Profit
Critique of the Gotha Programme
Manifesto of the Communist Party (along with Engels)
The Poverty of Philosophy
And, of course, Capital Vol I-III

Ceramics (roof tiles and pots) were manufactured on an industrial scale in Rome for example. They employed workers and produced massive numbers of products.
What is your distinction between employing people for money and capitalism?
Very interesting example! I'd say it's definitely a proto-Capitalist example, undoubdtedly. I wouldn't call it Capitalist out right, however, for a few reasons:
Ceramics manufacture was relatively unique among the entire Roman economy. The Roman economy was largely slave-driven.
Ceramics manufacture itself was technologically limited. The vast majority of what went into creating a pot, for example, was human hands, the Kiln was really the largest technical instrument. As a consequence, there wasn't continuous iterative improvement at voracious scales as is characteristic of Capitalism.
I would classify it closer to a large version of manufacturing workers, but certainly could have expanded into Capitalism had the Roman society at large developed similar structures, giving rise to a dominant bourgeois class and the abolition of slave labor in favor of wage labor proletarians. The context of the entire economy is critical.
I think I answered the differences between paying people in general and Capitalism specifically, but I also recommend Engels' Principles of Communism, the first few pages go over what makes Capitalism distinct from pre-Capitalist economic formations.
I was asking to clarify, because it sounded like your definition of capitalism was something like 'uses industrial machinery to allow for unskilled work.' By that definition, I agree that by definition capitalism didn't exist till after the industrial revolution, since industrial machinery didn't exist yet. But I disagree that capitalism requires industrial machinery.
Feudalism also employed some industrial machinery (water wheels for milling grain is one example). But the primary energy source was still muscle power, the primary product was agricultural produce, and the workers were peasants tied to the land, not mobile wage workers producing consumer goods.
Marxists consider these important distinctions that define entire historical periods, even if they're still both examples of class society.
Great points, kicking myself that I forgot to mention the key aspects of production being largely agricultural, and workers largely immobile, especially. The ability to set up factories in cities with close cooperation is what took the sparks to a blaze.
Absolutely, and thanks for your work in this thread. o7
No problem, you too comrade! o7
