Well these programs are not meeting the need. Ask the vets about what "help" they got from their program in regards to real issues they had. Most of their needs are neglected in favor of just beating them with the "programs fix" no matter the issue. In some cases the kids don't even have an issue.
However some people do have problems and to meet their needs will be a challenge. For a start we could get rid of the punitive think that seems so pervasive in this industry. Creating more passive controls for those who are dangers to themselves would help in regards to the conflict that results when you try to control someone. By passive I mean building environments around the child. Would you setup a daycare in a nuclear energy plant? No, so why have hard objects(floors, walls) in a facility with kids that bang their heads? And why remove a kid from the home, especially kids with developmental disabilities? We can take care of most of these kids at home if we are willing to sacrifice time and convenience.
The institutions of last resort have become the institutions of convenience when we are desperate, at our wits end, or when we just feel like being fucking cruel. Now we have a system of care that often places the ego of the facilities directors, or political backers, over the interest of the kids, and lets not forget about the powerful influence of money.
It sounds like me and you listen to different choirs. You listen to the lofty promise of the program while I listen to the broken reality of their collateral damage.
