Reply #3: To me, fiscal policy comes down to this:

[AP]

Do you think money should generally flow down to the middle class, and do you feel the gov't should stand as the policeman making sure that the corporations trying to run monopoliies and act negligently are sticking their hands in the pockets of citizesn? Or, do you think money should flow up to the wealthiest people in society and that the gov't should help grease the skids through regressive taxation, deregualtaiont, privatization, and the encouragement of monopolization by ever growing and concentrated corporate power?

Fiscal liberals believe in the former, fiscal conservatives believe in the latter.

Another way to describe the difference: Keynes is a fiscal liberal. Supply-siders are fiscal conservatives.
