Patch pocket sewing has been automated for years.[1] For standard products like jeans, most of the operations are performed on an assembly line with special purpose machines. Direct labor content of the pair of jeans shown is 12 minutes and 15 seconds.[2] Even at $20/hr, that's only $4. Most of the human labor is putting parts into machines and taking them out.
