The New York Times has a great article by Paul Krugman on the illogic of Bush's tax cut proposal. "The average American worker earns only about $40,000 per year; why does the administration, even on its own estimates, need to offer $500,000 in tax cuts for each job created? If it's all about jobs, wouldn't it be far cheaper just to have the government hire people?" Krugman wrote The Return of Depression Economics in the late 90's. It's still the best, most clearly written book on macroeconomics I've ever encountered.
