Supply-side economics is a hearty perennial, one that closely follows the election cycle. Every four years ambitious Republican politicians (and not a few ‘centrist’ Democrats) rediscover that the wealthy would like to pay less in taxes. But the rhetoric of politics does inhibit the wealthy, their kept intellectuals, and paid spokesmen from arguing their case directly. In democracies, even those resembling plutocracies, the rich must present their own interests as coinciding with the general good.
With this in mind, and yet still aspiring to a tax cut, the wealthy have lavishly supported ‘astroturf’ political organizations and ‘think tanks’ which, in turn, hire photogenic and eloquent spokespersons to present their case to the public. In its best form, the argument is that tax cuts for the rich will: (1) increase the national savings rate because the wealthy save a larger percentage of their incomes than others. This increased quantity of savings will (2) provide the funds required to spur business investment in plant and equipment. From this it follows that (3) supply-side tax cuts will have the effect of providing strong economic growth, which will “trickle down” to the “regular guy.” We are assured that not only are these propositions true, but that they were proven decisively during the Reagan Administration.
