I'm a little confused by the first part because yeah Marx never saw a modern factory but he was there at the beginning of industrialization. Marx collaborated with Engels whose family owned large textile factories. I think he saw what was coming and was saying that under capitalism the owners of these factories are going to be in charge of everyone else. Also that capitalism is inherently unstable and prone to cyclical crisis which empower the capitalists and impoverish workers. At least in the US, it appears to me he was correct.
