Robert Higgs has just provided additional excellent commentary affirming this very point. Using data compiled at the Heritage Foundation, Higgs notes,
[I]n 1962, 21.7 million persons depended on the programs they included in their index for benefits. By 2009, the corresponding number of dependents had grown to 64.3 million. Adding dependents not included in the Heritage study might easily increase the number to more than 100 million, or to more than a third of the entire population. Thus, the parasites verge ever closer to outnumbering their hosts.
