No. Children are not the bottleneck. Parents are. All the statistics we have say that children in homes where the adults value education and urge their children to learn do better, regardless of other circumstances. Unruly children are typically the result of parental neglect. There are many many examples among poor families of well-behaved children achieving a trajectory that raises them out of poverty within a generation. But it all has to do with the attitude toward education and behavior in the home.
The classic example is poor Asian immigrants that produce successful professionals within one or two generations. Strict behavioral expectations in the home, coupled with an attitude of parental sacrifice for their child's educational opportunities causes significantly better results decade over decade. But this is an attitude that often doesn't translate to many American households.
Vouchers might be one way to help, but it still requires parental involvement in creating the incentive for the child.
How would vouchers help? It's not like changing schools increases parental involvement. If that's your model the use of public money that makes sense is paying parents to be more involved.
