Here’s the problem:
The most effective tax policy is the one that strikes most of us as, superficially, the least fair: Provide a large cut in marginal tax rates, which benefit primarily the wealthiest. This little rebate is nothing more than cheap gimmick, because it ain’t enough for anyone to save. That, you see, is where the real multipliers exist - whether the savings go to banks, mutual funds, or (better still) risky venture capital, the dollars so invested multiply much faster than the dollar spent on immediate consumption.
The reason you want a reduction in marginal tax rates is precisely because it gives rich folks too damn much money to spend. Instead, they’ll invest.
In fact, there’s some research indicating that changes in tax policy don’t have much effect on rich folks’ spending - they spend a certain amount, and what’s left over they invest. Increase the amount available for investment, and that results in more wealth and job creation, which means that overall the entire system is better off, and indeed, tax receipts increase for governments. (This is particularly true for capital-gains taxes - raising rates results in asset fire-sales prior the rate increase, thus depressing asset prices and guaranteeing that government comes out behind.)
The fundamental fallacy behind much traditional “liberal” tax policy is that they assume (a) that tax policy doesn’t affect behavior, and (b) even if it does, everyone behaves the same. The problem is that the rich indeed are different from you or I, because their behavior has the greatest impact and because they invest rather than change spending.
Now, some wag is bound to ask if tax rates for the wealthy should be reduced to zero. No, of course not. And I’m not a flat-taxer either, I believe in graduated rates under which a majority of the citizens of this country simply don’t pay taxes at all. (In fact, I’d love a breakdown of how many people do, in fact, either pay no taxes or receive an Earned Income Tax Credit, which means they actually take more out each year than they put in.) What I do believe is that when you need a stimulus to wealth and job creation, you focus it where you’ll get the most results for everyone, even if on the face it’s counterintuitive.
Oh, and then there’s this little question of wealth. With the exception of estate and land taxes, by and large we don’t tax wealth in this country and that’s A Good Thing. You see, if we tax wealth, we force people to sell assets. That depresses asset values, which results in a downward spiral to the economy. Plus, it results in some real injustices - perhaps not for W.'s putative family-farmers, but for older people who suddenly can’t afford the property taxes on the modest home they’ve owned for 35 years.
Nope, on a superficial basis none of this is fair. But the effect of failing to view the economy dynamically results in Eurosclerosis, where the most dynamic economies (Britain, the Netherlands and Ireland) are those that have most rationalized and reduced their tax burdens. It works, and as imperfect as it is it results in the largest job creation around. And it even results in a pretty decent standard of living (ever reviewed what percent of the population has telephones, televisions and air conditioners?), even if it is highly unequal. It really doesn’t matter where the ceiling is provided that the floor is reasonably clean. Yes, there are holes by region (Appalachia, inner cities) and in such categories as health insurance (although frequently people misunderstand lack of health insurance as lack of health care, which most emphatically doesn’t follow). But the alternatives are worse.
