The goal is to reduce the size and scope of government spending, not to focus on the deficit. The deficit is the symptom of the disease.
The question is: How do we reduce spending from 25% of GDP, which is where Obama put us? The focus is on total government spending. Can we bring it down, in a reasonable and politically acceptable way? That's what the Paul Ryan plan does. It puts us on a gradual reform path to reducing the size of government.
