 Modern democracies, however, are different from the ancient polis in several important and pertinent respects. They are mass societies in which most people can have little individual impact on government and policy. They are complex, technologically-driven, highly specialized societies in which professionals (including lawyers, civil servants, and politicians) have much more expertise than laypeople. And they are liberal constitutional regimes in which individual freedom is protected--to various degrees--and government is deliberately insulated from public pressure. For example, courts and central banks are protected from popular votes. Once the United States had become an industrialized mass society, the influential columnist Walter Lippmann argued that ordinary citizens had been eclipsed and could, at most, render occasional judgments about a government of experts (see The Phantom Public, 1925). John Dewey and the Chicago civic leader Jane Addams (in different ways) asserted that the lay public must and could regain its voice, but they struggled to explain how.
