Yes, you can send money, letters, books and magazines. Private prisons are owned by a corporation and work under a contract with the agency that supplies them with inmates. They are paid by-the-inmate, for each day of incarceration. It is a controversial but effective means of incarceration.
The bigger problem is that these companies spend millions lobbying Congress promoting incarceration rather than rehabilitation. It's a onflict of interest for those seeking to reduce sentences and find a better way, especially first-time, non-violent offenders. But make no mistake prison is prison and the inmates can't really tell the different of who "owns" the facility.
