One of the original arguments for educating children in traditional public schools is that they are necessary for a stable democratic society. Indeed, an English parliamentary spokesman, W.A. Roebuck, argued that mass government education would improve national stability through a reduction in crime.
Public education advocates, such as Stand for Children’s Jonah Edelman and the American Federation for Teachers’ Randi Weingarten, still insist that children must be forced to attend government schools in order to preserve democratic values.
In principle, if families make schooling selections based purely on self-interest, they may harm others in society. For instance, parents may send their children to schools that only shape academic skills. As a result, children could miss out on imperative moral education and harm others in society through a higher proclivity for committing crimes in the future.
However, since families value the character of their children, they are likely to make schooling decisions based on institutions’ abilities to shape socially desirable skills such as morality and citizenship. Further, since school choice programs increase competitive pressures, we should expect the quality of character education to increase in the market for schooling. An increase in the quality of character education decreases the likelihood of criminal activity and therefore improves social order.
There are only three studies causally linking school choice programs to criminal activity. Two studies examine the impacts of charter schools and one looks at the private school voucher program in Milwaukee. Each study finds that access to a school choice program substantially reduces the likelihood that a student will commit criminal activity later on in life.
Notably, Dobbie & Fryer (2015) find that winning a random lottery to attend a charter school in Harlem completely eliminates the likelihood of incarceration for males. In addition, they find that female charter school lottery winners are less than half as likely to report having a teen pregnancy.
Note: A box highlighted in green indicates that the study found statistically significant crime reduction.
According to the only causal studies that we have on the subject, school choice programs improve social order through substantial crime reduction. If public education advocates want to continue to cling to the idea that traditional public schools are necessary for democracy, they ought to explain why the scientific evidence suggests the opposite.
Of course, these impacts play a significant role in shaping the lives of individual children. Perhaps more importantly, these findings indicate that voluntary schooling selections can create noteworthy benefits for third parties as well. If we truly wish to live in a safe and stable democratic society, we ought to allow parents to select the schooling institutions that best shape the citizenship skills of their own children.
