One important result of this capital migration is that the burden of the corporate income tax, over time, shifts to workers: with a smaller capital stock to employ, workers are less productive and earn lower real wages. In a 1996 survey, public finance economists were asked to estimate what percentage of the corporate income tax in the United States was ultimately borne by owners of capital. While their answers varied, the average response was 41 percent, meaning that the professional consensus is that more than half the burden is eventually shifted from owners of capital to workers or other groups.
