But he expresses deep disappointment with Bush. “My biggest frustration remained the president’s unwillingness to wield his veto against out-of-control spending,” Greenspan writes. “Not exercising the veto power became a hallmark of the Bush presidency. . . . To my mind, Bush’s collaborate-don’t-confront approach was a major mistake.”

Greenspan accuses the Republicans who presided over the party’s majority in the House until last year of being too eager to tolerate excessive federal spending in exchange for political opportunity. The Republicans, he says, deserved to lose control of the Senate and House in last year’s elections. “The Republicans in Congress lost their way,” Greenspan writes. “They swapped principle for power. They ended up with neither.”

When Bush and Cheney won the 2000 election, Greenspan writes, “I thought we had a golden opportunity to advance the ideals of effective, fiscally conservative government and free markets. . . . I was soon to see my old friends veer off to unexpected directions.”

He says, “Little value was placed on rigorous economic policy debate or the weighing of long-term consequences.” The large, anticipated federal budget surpluses that were the basis for Bush’s initial $1.35 trillion tax cut “were gone six to nine months after George W. Bush took office.” So Bush’s goals “were no longer entirely appropriate. He continued to pursue his presidential campaign promises nonetheless.”
