I think this is a case of language being context-dependent and how the exact meaning of `inspired' depends on its use. I'll elaborate a bit but ultimately I'll say this: Marx was inspired by the world around him, which consisted of poor worker conditions [0]. We can say this confidently because recent evolution in the study of ideology tells us exactly this: We are a product of our social and material environment, something we can't escape [1]. Anyway, my point is that the way CamperBob2 discusses the topic of Marx's inspiration makes it sound like a fundamental axiom of Marxism is the poor conditions of the working class and specifically their conditions during working hours. If this was true, we'd be able to conclude that the predictions of Marx [2] would be disproved by the gradual removal of these (poor) worker conditions. We can show this isn't true by appealing to our shared knowledge about the world, where global inequality is increasing and where worker conflict was at the center of an (almost) successful presidential campaign. We can also show this with empirical data, where our shared knowledge may fail us. For instance, Marx predicted that the global rate of profit would continue to fall, the reasons for which are beyond the scope of HN. This has been demonstrated to be true by many Marxists along the years, of whom the most prominent since the rise of the IT-worker is the economist Andrew Kliman [3].
