Hours worked is irrelevant. The lifestyle afforded by $21,480 a year is terrible. That's barely enough to support a single person let alone a spouse/family. This means that 40% of the workforce are most likely dependent on someone else. Either another individual or the government as evident in the 47.7 million Americans who receive food stamps. The workforce has changed since 1968. Full time jobs are not as easy to come by now as they were back then. There is indeed underemployment with people working fewer hours but that doesn't change the fact that 40% of the population is living off less than a 1968 minimum wage.
