********************************************** ABSTRACT: In a discussion "Charter Schools: A Marketplace for Profits or Ideas?" Bill Moyers' <http://bit.ly/1feQ5iw> interviewed Diane Ravitch, who stated: "The lure of getting federal money made many states change their laws to open the door to many, many more charter schools. . . . . . . Public education is becoming big business as bankers, hedge fund managers, and private equity investors are entering what they consider to be an 'emerging market.' As Rupert Murdoch put it <http://bit.ly/1pAwGMh> after purchasing an education technology company, 'When it comes to K through 12 education, we see a $500 billion sector in the US alone' . . . . . . I think what's at stake is the future of American public education. I believe it is one of the foundation stones of our democracy: So an attack on public education is an attack on democracy." See also "Here is the Bill Moyers Interview in Full" [Ravitch (2014)] at <http://bit.ly/1mFTAmo>. Over 4 decades ago economist Albert O. Hirschman (1970) in "Exit, Voice, and Loyalty: Responses to Decline in Firms, Organizations, and States" <http://bit.ly/11QKoRB>, made a case against charter-schools similar to that made by Ravitch. He first quoted the conservative economist Milton Friedman who argued that SCHOOL VOUCHERS SHOULD REPLACE THE CURRENT PUBLIC-SCHOOL SYSTEM, writing "Parents could express their views about schools directly, by withdrawing their children from one school and sending them to another."
Hirschman then countered (my CAPS): "[Friedman's opinion] is a near perfect example of the ECONOMIST'S BIAS IN FAVOR OF EXIT AND AGAINST VOICE: In the first place, Friedman considers withdrawal or exit as the 'direct' way of expressing one's unfavorable views of an organization. *A person less well trained in economics might naively suggest that the direct way of expressing views is to express them!* Secondly, the decision to voice one's views and efforts to make them prevail are contemptuously referred to by Friedman as a resort to 'cumbrous political channels.' But what else is the political, and indeed the democratic, process than the digging, the use, and hopefully the slow improvement of these very channels?"
