Among the arguments made by advocates for charter schools is that they expand consumer choice and that given the state of education in many inner-city minority communities experimentation with alternatives can only help the situation. As buzz words, choice and experimentation always sound good. After all, we know about the disappointing performance of many students in inner-city schools under the current educational system so why not try something else?
Unfortunately, we already know what will happen if private-for-profit charter school companies take over K-12 education in the United States because for-profit proprietary companies have already successfully invaded what used to be called "higher education." These companies have defrauded the government, left families deep in un-repayable debt, and cheated students out of an education.
Higher ed and K-12 are connected ~ what goes down in one, affects the other; "innovations," policies, programs, etc. implemented in one domain will eventually come home to roost in the other, trickle up or trickle down. It behooves each to trend watch the other.
