Since at least the Great Depression, most economists and most Americans appear to have accepted that the government should play a significant role in managing the economy by adopting policies that stabilize employment, encourage economic growth, and control inflation. Nevertheless, Americans have always differed on the proper form and extent of government intervention, and these differences may have sharpened in recent decades. In general, policy attitudes appear to have sorted into liberal and conservative clusters and aligned more fully with partisan preferences (Abramowitz 2010).
