You have that right. There is a serious problem that is affecting all advances economies. What do we do with the people in the bottom third of the IQ scale. These people cannot become programmers/IT techs/network analysts or even electricians or plumbers. There was a time when a strong back and a willingness to work was enough to provide a decent living. Those days are gone. As the cost of labor has increased these people have been priced out of the market.
I don’t have an answer but the problem is real and getting worse as technology replaces labor in ever more occupations.
Politicians figured that out decades ago. Turn them into voters.
