Speaking at the White House on June 25, Vice President Joe Biden claimed that a higher federal minimum wage was practical and long overdue. "Just pay me [for] minimum wage what you paid folks in 1968," Mr. Biden said, echoing the argument numerous labor unions, left-wing think tanks and activist groups have made.
The logic goes something like this: Had the minimum wage tracked inflation since 1968, it would today be over $10 an hour, so Congress should seek to bring it up to at least that amount. There are two problems with this logic. First, it is inconsistent with other Labor Department inflation data. And second, it presumes that entry-level employees can't get a raise unless the government gives them one.
The federal minimum wage was first set in 1938 at 25 cents an hour. Had it tracked the cost of living since, it would today be $4.07 an hour, based on Labor Department data and the Bureau of Labor Statistics' inflation calculator. This is the only logically consistent "historic" value of the minimum wage, and it's 44% less than the current amount of $7.25.
Advocates of a higher minimum wage arbitrarily selected 1968 as the historical reference point. It's no wonder: That's when federal minimum wage hit its inflation-adjusted high point.
How about picking other arbitrary years to track the minimum wage and inflation? If you used 1948 instead of 1968, the minimum wage's inflation-adjusted value would only be $3.81 an hour. If you chose 1988, the adjusted minimum wage would...
