RealClearPolitics has an interview with Senator Toomey of Pennsylvania, and asks him whether 5% growth is a reasonable goal:
If we had really dramatic tax reform, if we got our fiscal house in order, if we reform the big entitlement programs, if we rein in the regulators, and if we expand trade, I think it is entirely possible. You could average that. We could have a wave of innovation and investment that could very well produce something like that and it's a good goal to have.
