We have been cutting taxes for the past ten years. It has not worked.
First: The key is cutting SPENDING. As long as the government spends enormous amounts of money the value behind that money is sucked out of the public sector economy, depressing it, regardless of whether this is done by taxes, inflation, or borrowing. Spending has EXPLODED over the past ten years - especially with the "bailouts".
The different modes of ripping off the people hurt the economy in somewhat different ways, and some have greater "hurt multipliers" than others. But the value bled out of the economy to be squandered on non-producing (or under-producing) government projects sets a minimum level of damage.
Second: Most of the so-called "tax cuts" weren't. They were typically government giveaways administered through the IRS. To be a "tax cut" of the form that stimulates productivity it must be a cut in the RATE of tax on a FUTURE activity, and must be passed into law or regulation in time to influence the taxpayer to make a decision to perform the action that is now taxed less. Things like a lump sum given to each tax filer and passed into law after the taxpayer has already made all his economic decisions and done all his actions fails on both tests, no matter how many politicians call it a "tax cut".
