"it is simply untrue that there is a shortage of low skilled labor in the United States. There are more than 30 million low-wage workers in the workforce. More specifically, Black teenage unemployment in the United States (men ages 16-19) is approximately 35%. The New York Times recently reported on the “deepening plight” of black men."
Change the age range, and narrow the gender to males, and you get a more creditable stat about black unemployment. But that stat was the same 20 years ago, maybe worse. In fact, it was probably worse.
