Some people say that it’s okay for machines to take jobs, because we’ll get jobs fixing the machines. just from looking around, do you think that most working americans are earning a living by fixing farm equipment.

no, I don't think they are making any living from fixing farm equipment.

Explanation:

There is a high chance that when those machines broke people who will be called to fix them are the already existing contractors who will bring their own mechanics .

No one will be hired to come and fix those machines , the job is likely to go to someone who already has a job.

In a way these machines do cut down employment opportunities for the ordinary Americans .

One machine cover the work that can be done by 10 or more people and even if a person is hired to fix it, it won't amount to the number of people who would have been hired to do the job that is now done by machines .
