What hogwash. Americans have skills at every point on the employment spectrum. And the above is putting out the same sort of nonsense where the same open borders advocates claim there is a big STEM worker shortage, when facts show that there is a surplus and many cannot find work in the field for which they prepared.
And, unfortunately, many of our lower skill citizens are on one or more poverty programs, and taking a lower paying job would yield them less than government programs.
With all the Americans who are unemployed, underemployed and on government poverty programs, there is probably no shortage of workers in any field.
The only way you can make the case that there is a worker shortage is if we were at zero unemployment (or effectively zero, when you exclude the disabled and the shiftless). Since we aren’t, that kind of claim is just laughable.
