Edmund Phelps underscores the importance of earning a respectable wage to foster self-worth and responsibility. He shows that earning such a wage has been increasingly hard for those at the low end of the wage distribution as productivity has come to rely more on knowledge and skills and less on brawn and hard work. A crucial task for our economic and political system, Phelps asserts, is to devise methods to help less productive workers draw a reasonable wage, thereby reintegrating them into the economic mainstream. Phelp's solution is a graduated schedule of tax subsidies to enterprises for every low-wage worker they employ. As firms hired more of these workers, the labor market would tighten and pay levels would rise. Ultimately the program would be largely self-financing, because its cost would be offset by reductions in the cost of welfare, crime, and medical care - as well as by taxes paid by formerly unemployed workers. Rewarding Work is an essay in what could be called economic engineering - in this case, the engineering of wage structures to help low-wage American workers achieve self-sufficiency and self-respect.
