Several problems with this. First, automation leads to unemployment. A factory that once employed hundreds of people can now be run by robots and a few overseers and a repair crew. This would not be a problem if the reduced costs and increased profits were passed on to the formerly employed, but this is not the case. Rising overall production does not necessarily lead to a higher standard of living for the average person.
On the short term this may be true in the factory, but not true by looking outside. And on the long term, maybe more jobs can be created INSIDE the factory.

However, in general as a owner, you don't expect to reduce employement. You want to maximize profit.
If there is demand for your product, you will increase the number of robot, so increase the production, and so increase the number of overseers, and repair crews.
You forget also all business that got created like Trainers for the repair crews, Developers for the robot, and all jobs needed for the creation of such robot.
Jobs are moving, if you take the example of one factory and don't look outside, sure employment got lost in the factory, but they reappear in other forms elsewhere.
Sure it is bad if you worked in the factory. But don't expect me, as a developer that profit from this technological shift, to pay for their loss. They would have not pay me if computing were a fad and I lost my time learning everything about automation. And I did not expect them to do it.
