Krugman points out that the inflation adjusted wages of non-supervisory workers in the retail field in America has declined by 30% since 1973. He says there are no adverse effects on unemployment because workers in retail are not competing with workers in other countries as happens in manufacturing. They are also some of the lowest paid workers to begin with, and the numbers are not small. One estimate is that here are 30 million workers who would benefit from an increase in the minimum wage from the current level of $7.25 to $10.10. State by state comparisons provide proof of this as no evidence of losses in employment are to be seen when one state has raised the minimum wage and another neighboring state has not. Germany is facing a similiar problem of low paid temporary workers and a new coalition government is planning an increase in the minimum wage in 2014 as a response to increasing inequality and disparity in incomes developing in the last two decades.
