What are some exceptions to the federal minimum wage?

Explanation:

It keeps the states from setting the minimum wage at less than that amount. States can choose to set their state minimum at a higher amount, but not a lower amount.

Often states with a higher minimum wage, set it higher because the cost of living is higher in some states than others. If the cost of living is the same or lower than the federal, the states often do not pay more than the federal amount.
