Liberal arguments? Manufacturing itself does operate in cycles and cannot trend downward infinitely unless the entire world suddenly turns Luddite. Even automated manufacturing requires a vibrant repair and maintenance industry; factory machines are not self-repairing organisms that can be back to good working order after a night of sleep. (Never mind the fact that automation was the beginning of the Industrial Revolution to begin with.)
What seems to be ignored here is the importance of manufacturing to national security, never mind the unfriendliness of liberals to manufacturing since the end of WWII what with piling on the regulations and taxation (which kills new start-up businesses within a year for the most part in the USA).
Problem is, if you service (repair or maintain) a machine, your job is not counted as a “manufacturing job,” unless by odd chance you actually work for the manufacturer itself.
Did they factor the jobs in intercountry shipping and export shipping as well?
Did they factor the fact that the jobs would have an internal multiplier effect?
Or that instead of say having 10 low skilled factory workers you may have 4 high skilled technitians who need 2 babysitters and other peripheral service jobs are created to support them, etc etc...
CNC and CAD have changed the world. They produce products better and faster. The labor input per unit is less. The quality and finish is superior.
The once skilled machinists are no longer needed to the same degree. The maintenance types include highly skilled computer savvy to setup and render TLC to the various auto systems in the machine.
The operative word is number 5. Changed. the only constant in life of individuals or nations is change. The way to deal with change is to embrace it and move forward. That is not to say all change is good, but it must be delt with in one way or another. Obama et al are cancerous change and must be surgically removed
True, but every manufacturing facility I know has reduced their maintenance staffs over the years. The last place I worked they reduced it from 17 to 14 while adding new machines and maintaining the old ones. Where I work now the place went from ten to three - all of us maintaining the same old machines that are at least ten years old.
One of my co-workers last places went from eight to one. Yes. He was expected to work at least 60 hours a week minimum.
"Vibrant" you say. I say you're uninformed.
