Power naturally converges to a center, for it is ineffective when divided, diluted, and spread, as in Poland under the liberum veto; hence, the centralization of power in the monarchy by Richelieu or Bismarck, over the protest of feudal barons, has been praised by historians. A similar process has centered power in the federal government in the United States; it was of no use to talk of “states’ rights” when the economy was ignoring state boundaries and could be regulated only by some central authority.
