That’s what happens anytime we see a new form of automation, companies don’t reduce work hours and keep the pay the same, they try to increase production and the workers that were replaced will be made to do some other menial task machines can’t do, and they will also be made to work 40hrs a week.

I understand your point, and it is probably true for some companies and some jobs. However, it doesn't apply to telephone switchboard operators, bank tellers, movie projectionists, pinsetters, lamplighters, elevator operators, etc. These are jobs which don't have an impact on the production or manufacturing of a product.

I always bring this up, automation is what made slavery profitable in the south. When the cotton gin was invented slaveowners didn’t start using less slaves for the same out put of cotton.

I understand that you're talking about the cotton gin because it improved productivity, but the cotton gin used in the early 1800's is an example of mechanization, not automation. It's like a reel lawnmower, which is an improvement over a scythe, but there's nothing automatic about it. This distinction doesn't make much difference here, in the context of productivity.
