Minimum wage was established at $0.25 in the FDR era, which is significantly lower when adjusted for inflation than today's federal minimum wage (which we all agree isn't a living wage).
According to CNN, the highest the minimum wage has ever been when adjusted for inflation was less than $12, still not a living wage.
