How was class structure reformed by industrialization?

Two classes that benefited during the Industrial revolution were the "middle" and “upper” classes, i.e. the classes that had both the wealth and the success. The middle class was composed of businessmen and other professionals, while the upper class was the "working" class and was not well off, because many were replaced by machines in factories.
Most people could afford the goods, and the prices were additionally lowered, so that everybody could enjoy the comforts of the new products being made.
