It kills profiteers that all the money-and it is considerable- that runs through public schools to educate all children in America cannot somehow be tapped FOR profit. Enter charter schools, mandated standardized tests, standardized curricula and etc and you can see ways that is happening.
The goal of teaching all children regardless of their circumstance is lofty and some would say grandiose. There are many real problems and challenges. The profiteering, no matter how nobly framed, generally seeks to tap the dollars and is shockingly indifferent to those core difficulties.
There are no easy answers to, "What should a 21st century education look like?" And, "How to best deliver it to this diverse group of kids some of which come to school wounded?"
