"If we started in 1960 and we said that as productivity goes up, that is as workers are producing more, then the minimum wage is going to go up the same. And if that were the case then the minimum wage today would be about $22 an hour," she said, speaking to Dr. Arindrajit Dube, a University of Massachusetts Amherst professor who has studied the economic impacts of minimum wage. "So my question is Mr. Dube, with a minimum wage of $7.25 an hour, what happened to the other $14.75? It sure didn't go to the worker."
Dube went on to note that if minimum wage incomes had grown over that period at the same pace as it had for the top 1 percent of income earners, the minimum wage would actually be closer to $33 an hour than the current $7.25.
It didn't appear that Warren was actually trying to make the case for a $22 an hour minimum wage, but rather highlighting the results of a recent study that showed flat minimum wage growth over the past 40-plus years coinciding with surging inequality across a number of economic indicators.
Warren went on to argue that raising the federal minimum wage to over $10 an hour in incremental steps over the next two years -- a cause championed by President Barack Obama in his State of the Union address and since taken up in the Senate -- would not be as damaging for businesses as some critics have argued.
