The law states that full employment is one of four economic goals, in concert with growth in production, price stability, balance of trade, and budget, and that the US shall rely primarily on private enterprise to achieve these goals. Specifically, the Act is committed to an unemployment rate of no more than 3% for persons aged 20 or over, and not more than 4% for persons aged 16 or over (from 1983 onwards), and the Act expressly "allows" (but does not "require") the government to create a "reservoir of public employment" to affect this level of employment. These jobs are required to be in the lower ranges of skill and pay so as to not draw the workforce away from the private sector.
