If so, continue on. The Constitution assigns specific responsibilities to the federal government. Like it or not, that means the federal government's powers are limited to those addressed in the Constitution. That's how I'll run things. See the Big Shift for details.
State governments are another matter.
They're free to tackle anything they wish within the limits of their constitutions and, hopefully, the will of the people. This is where the majority of debate on government involvement should be taking place. It's important to remember that every time the government funds a project we lose a little of our freedom. Sometimes the assault is direct, as in gun control, other times it's indirect in that you're now forced to pay for a program you may not believe in. The potential rewards must be worth the loss of freedom.
