“Strange” is what Robert Samuelson concluded, too. He is your source; however, his conclusions are a far cry from yours :

“One of the perplexing economic questions these days is why wage growth has been so slow despite the longest economic expansion in U.S. history (now in its 11th year).

By conventional wisdom, tight labor markets should be raising wages much faster than is occurring. The logic is simple. With low unemployment, workers can quit their jobs and find something better. Companies have to boost wages to attract new workers or keep the ones they’ve got. This is Economics 101.

The trouble is that Econ 101 isn’t behaving as expected. Corrected for inflation, average hourly earnings in November were up a meager 1.1 percent from the previous November, according to the Bureau of Labor Statistics.”(Wash Post 12/15/19)

So your conclusion is dubious — at best.
