How much will minimum wage be in 2020?

In the United States, President Obama recently raised the minimum wage for federal employees and federal contract workers to $9 per hour. This does not affect private employers, for whom the federal minimum wage remains $7.25. Many states have higher minimum wage laws. In the 2014 State of the Union Address, Obama proposed raising the national minimum wage to $10.10, however this is not currrently enacted.
