From what I understand those programs can only go so far in providing for youth in terms of opportunities, I know a few people involved in such programs that feel that way. Biggest problem with said strategy is how to create the incentive for youth to attend. One thing I remember is a similar effort made back in Cuba, there was a special set of schools that targeted 18+ youth that had dropped out of school. The incentive was that they would be paid to attend school, a meagerly sum but it was only a few hours classes a day. Most went because it was easy money and kept them out the military service, which they were all trying to dodge.
Wish we could implement something like that here, but I already hear the cries of "Communist" "He is trying to turn this country into a socialist cesspool" or some teabagger crazy like that.
