I have been a long time contributor and occasional collaborator with Free To Choose Network. My son is on its board of directors. I believe their work is very good.
You may find some of the videos with which I have been involved interesting:
All of these have aired on PBS.
Be on the lookout for another PBS program, The Human Cost of Welfare, which will be soon be part of PBS’s Chasing The Dream series.
I am also a supporter of the DEAD WRONG series of videos.
