The reforms propose that minimum wage is indexed to the GDP per hour or income per hour, rather than the CPI (prices), in order so that workers receive the same share of revenue per hour over time, and their pay is not devalued by inflation. Prices do not increase at the same rate as GDP per hour due to increases in efficiency and the decrease in prices in real terms.
