Minimum wage:

Calculated in real 2012 dollars, the 1968 minimum wage was the highest at $10.51. The real dollar minimum wage (red squares) falls during periods Congress does not raise the minimum wage to keep up with inflation. The minimum wage increased in three $0.70 increments—to $5.85 in July, 2007, $6.55 in July, 2008, and to $7.25 in July 2009. The 2012 minimum wage is equal to what was paid in 1960.
