In an interview on NBC's "Meet the Press," Greenspan expressed his disagreement with the conservative argument that tax cuts essentially pay for themselves by generating revenue and productivity among recipients.
"They do not," said Greenspan.
"I'm very much in favor of tax cuts but not with borrowed money and the problem that we have gotten into in recent years is spending programs with borrowed money, tax cuts with borrowed money," he said. "And at the end of the day that proves disastrous. My view is I don't think we can play subtle policy here."
The comments from the former Fed chief were an elaboration of a position he outlined in an interview earlier in the week. Speaking with PBS' Judy Woodruff, Greenspan expressed his opposition to passing legislation that would hold tax rates steady (under law the tax cuts Bush passed ten years ago are going to expire, thereby bringing rates back to Clinton-era levels). President Obama has pledged to continue the tax breaks for those individuals making under $200,000 and those families earning less than $250,000.
But Republicans want the entire package kept in place. Even so, they have declined to say how they would pay for it, saying, in part, that keeping the Bush tax cuts in place will pay for itself.
In addition to throwing cold water on that theory, Greenspan also weighed in on broader economic issues and trends. The former Fed Chairman relayed some sobering economic predictions, saying he expected the nation's unemployment rate to remain at its current level, mainly because there were few tools left to change it.
"I see it [as] we just stay where we are," he said. "There is a gradual increase in employment but not enough to reduce the level of unemployment ...There is nothing out there that I can see which will alter the trend or the level of unemployment in this country."
