"Keynes himself had in his day been known to make some fairly radical noises, for instance, calling for the complete elimination of that class of people who lived off other people's debts—"the euthanasia of the rentier," as he put it—though all he really meant by this was their elimination through a gradual reduction of interest rates. As in much of Keynesianism, this was much less radical than it first appeared. Actually, it was thoroughly in the great tradition of political economy, hearkening back to Adam Smith's ideal of a debtless utopia but especially David Ricardo's condemnation of landlords as parasites, their very existence inimical to economic growth."
