This is an informative look at private school success in other countries. It contains excerpts from a series called School Inc. which is available on the Free To Choose Network on YouTube. I have subscribed. Their content is also available on Prime Video, and their own Roku channel. Here is their website: https://www.freetochoosenetwork.org/
In addition to School Inc., there are series by Milton Freedman, Walter Williams, Thomas Sowell and others.
