The End of Liberalism: The Second Republic of the United States

The main argument which Lowi develops through this book is that the
liberal state grew to its immense size and presence without
self-examination and without recognizing that its pattern of growth had
problematic consequences. Its engine of growth was delegation. The
government expanded by responding to the demands of all major organized
interests, by assuming responsibility for programs sought by those
interests, and by assigning that responsibility to administrative
agencies. Through the process of accommodation, the agencies became
captives of the interest groups, a tendency Lowi describes as
clientelism. This in turn led to the formulation of new policies which
tightened the grip of interest groups on the machinery of government.
