The recent attacks by parents and politicians on our public schools are poisoning public education. Many states have recently empowered private education institutions by supporting charter schools, homeschooling, and state-funded vouchers for students to attend private schools instead of their local public schools.

Proponents argue that the declining quality of student performance in public schools warrants giving parents a choice where to educate their children. They often cite parents who want to enrich their children’s education, but cannot pay for it.

Such student outcomes are self-fulfilling In Iowa when public schools are starved.
