Do assembly line dramatically cut cost of manufacturing goods because it allowed skilled workers to work fast

Answer 1

Almost, because it allowed less skilled workers to produce goods fast with an acceptable level of quality.
Most assembly lines are geared to a "lowest" common skill level, not a high level of skill as your questioned implied.

With assembly lines it requires less skill of the worker, and thereby and cheaper worker, who can produce more skills faster than the expensive worker. Very few companies will keep an expensive work if they believe a cheaper worker will produce the same quantity. Only a few good companies understand the importance of a strategically placed highly skilled worker.

Answer 2

Close, but not quite. The issue here is economic specialization and division of labor.

Let's say you're manufacturing pencils, and each worker has to make the whole pencil himself. It might take him all day to finish one. But if the workers specialize in certain aspects of pencil-making they can cooperate and make many more pencils per day.

So, assembly lines dramatically cut the cost of manufacturing goods because it allows specialized workers to cooperate.
