My brilliant plan to create prison reform: Every time the state wants to force a human being into a locked cage, they need to find a volunteer to be locked in a cage for the same amount of time as the person being involuntarily locked away. The forcibly imprisoned and voluntarily imprisoned must be imprisoned in the same facility, but are not informed who their imprisoned partner is. The volunteer cannot be paid for their service, they must elect to do it because of their glowing sense of civic duty. Prison guards may not have any access to information about whether or not an imprisoned person is a convicted offender or volunteer. Upon going in, volunteers must post a bond equal to 10% of their total wealth. If they disclose to any prison employee that they are a volunteer, they are discharged from prison immediately (a new volunteer must be found, if one is not available, the forcibly imprisoned person is discharged immediately) and forfeit the bond. 90% of the forfeited bond will go to the imprisoned person they are volunteering for, 10% of the bond will go to the prison employee that they disclosed to (as a reward for the employee reporting their serious offense). Bonus points: The volunteer must be sourced from the inverse wealth percentile as the potential involuntary prisoner (i.e. if you want to lock up someone from the bottom 10th percentile of wealth, you must find a prison volunteer from the top 90th percentile of wealth). Since prisons are such a wonderful peaceful place where troubled folks are taken care of and rehabilitated (couldn't we all use some quiet time for reflection?), finding plenty of volunteers should be no problem. I am certain that many wealthy scions of public society will volunteer for life imprisonment due to their great concern for civil society.
