Why won't this car move, and how can we fix it?

Please look at the simple illustration below.  The question to answer is why won't this car move?  How can we change this?  See the answers below.

Democrat:  The car won't move because of George W. Bush.  We should hit the pedal harder!

I'm sorry, Mr. Democrat. That is incorrect. 

Republican*:  The car is out of fuel, so hitting the pedal is pointless.  Fill the car with gas.

This is correct!  You see, you can't spend your way out of debt, and you can't create wealth by creating disincentives for productivity anymore than you can make an empty gas tank propel a car by slamming the gas pedal. 

*note: a 3 year old child could also get this answer correctly, as long as he/she has not been taught to think like a statist Democrat.
