@TooOld4School In the beginning of the 20th century they said exactly the same thing: “too bad that we no longer need all of that unskilled labor for our farms, we’re modern now, we need skilled factory workers”. Most of the jobs that need to be filled in the USA are NOT skilled jobs, or at least not the jobs for the type of skills that you seem to think would make the USA a better place.
If the USA did not lack so many unskilled workers, there would not be so many unregistered non-citizens working in these jobs. There is a lack of people working in the professions like electricians, carpentry, welding. There are people lacking in entry level tech jobs.
There are more jobs at the low-skilled and entry level positions that need filling than skilled positions and positions of manager and higher.
