School Choice - Charters, Competition & Deregulation?

Do we really want any further school initiatives that subject public education, our schools, our students, and ultimately the foundation of our democracy to the same market forces that produced our current economic crisis? What form will high risk speculation, mysterious financial instruments, derivatives, and credit swaps take in a deregulated public education sector? Or Ponzi schemes for that matter? Can there be any doubt that opening the huge K-12 education institution - and its tempting coffers - to the private sector will lead to the same kinds of abuses that got us into the mess we're in? If we study the history of deregulations gone bad - remember the S & L crisis, Enron, Worldcom, Merrill - perhaps we can keep the "greed is good" contagion from our children's education.
