Yes he was against public schools.'' Participants at the Koch Network gathering, Hohmann reports, spoke of ESAs being instrumental in redirecting public school funding to an array of privately-controlled alternatives to public schools, including “technologies” that let parents pick and choose private classes or tutors, teacher-less computer based instructional programs often called “personalized” or “customized” learning, and “micro-schools” that substitute computer software platforms for the traditional shared-space of a public school led by professional educators.''

Oh and you are wrong it seems. He was actually for roads,lol. He was against public transit. Which I would disagree with. Here's an excerpt.
