A Primer on the Federal Minimum Wage – NPR
Since the last federal increase in September 1997, from $4.75 to $5.15, the purchasing power of the minimum wage — after accounting for inflation — has deteriorated by 20 percent. Adjusted for inflation, the value of the minimum wage is at its lowest since 1955.
The Estate Tax and Extension of Tax Relief Act of 2006, H.R. 5970, which passed the House on July 29, raises the minimum wage for most employees. But for many employees in seven states, H.R. 5970 means a wage cut. Section 402 of the bill strikes down state laws that require employers to pay a full minimum wage without relying on tips from customers to reach the minimum level. States that have those laws will see the minimum wage for tipped employees fall as much as $5.50 per hour.
