One has to watch this video to believe it, in which Mitt Romney says that "classroom size was irrelevant to the quality of education."
I grew up about five miles from Cranbrook, the prep school that Romney attended (at the time Mitt it was known as the Cranbrook School for Boys; Ann Romney (née Davies) attended the Kingswood School for Girls. They are now combined). While I did not go there, I have been to the campus many times, to enjoy the wonderful architecture of Eliel Saarninen. It is an amazing place.
It currently costs $28,300 for one year for grades 9 through 12.
