A lack of concern about ethics permeates our government at all levels. Although there are lots of exceptions, and no one is perfect, overall, the quality of leadership at all levels and institutions is appalling. See factcheck.org and ethicsalarms.org for examples. These sites are not perfect, but they seem relatively non-partisan and reliable to me. See the list of tools for Ethical Decision-Making here. See Also "unethical rationalizations and misconceptions."
