The cost of environmental regulations are in part to blame for the slow growth in worker’s wages.
According to the 2005 Economic Report of the President, the growth of real output declined because annual labor-productivity growth slowed from 2.5 percent (prior to 1973) to 1.5 percent (from 1973 to 1995). Consequently, real weekly earnings — what workers took home in inflation-adjusted dollars — actually decreased during much of the latter period.
Although the oil-supply shocks, stagflation and price controls of the 1970s have often been blamed for inaugurating the economic slowdown, environmental regulations — particularly air- and water-pollution compliance — also took a heavy toll. In a study published in the 1995 Yale Journal on Regulation, economist James C. Robinson (currently with U. C. Berkeley’s School of Public Health) found that between 1974 and 1986, manufacturers’ direct costs of complying with environmental regulations had increased to just over one percent of the value of manufactured goods. Furthermore, multifactor productivity — the efficiency of labor, machinery, and other inputs working together — had fallen about 11.4 percent short of where it would have been without the edicts of the Environmental Protection Agency (EPA).
The unintended consequences of restricting business and economic growth is that employers have fewer resources, capital, with which to pay higher wages. There is a price for everything. Whole article here.
