There is never a good time to raise the minimum wage. Just ask the people working in low-skilled jobs that are laid off as a result.
Now is a particularly bad time. Yet the federal minimum wage is scheduled to rise to $7.25 on July 24, the third step of a $2.10 increase enacted in 2007. In more than half the states, the minimum wage already exceeds the current national minimum of $6.55 an hour.
