“…the output of power looms was certainly greater than that of the handlooms, but the handloom weavers produced higher quality cloths with greater profit margins.” [1]
The same can be said about machines like the water frame. It was great at spinning coarse thread, but for high quality/luxury textile (ie. fine fabric), skilled (human) spinners did a much better job. You can read the book Blood in the Machine for even more context.
