US has had a labor surplus for decades, not a shortage.
Wages are being artificially supressed by corporate America by oversupplying the US workforce via mass immigration.
Wage-fixing is a Federal crime.
“To analyze how large influxes of immigrant workers, in this case, construction workers, impact the market, the Los Angeles Times studied the Southern California building trade. The Times wrote that over a few decades, construction workers went from being majority union, and majority U.S.-born, to majority immigrant. In the article conclusion, journalist Natalie Kitroeff wrote, “Nonunion shops made aggressive inroads into home building with workers who had less experience. The result: Today slightly more than 1 in 10 construction workers are in a union, compared with 4 in 10 in the 1970s….an influx of immigrants who would work for less made it easier for builders to quickly shift to a nonunion labor force…” A footnote: in a relatively short time, immigration played a leading role in eliminating solid, blue-collar United Brotherhood of Carpenters jobs that paid middle-class wages, offered health care, paid vacations and pensions”.
