Patrick Fleenor and Scott A. Hodge:

One of the biggest obstacles facing President Bush’s Advisory Panel on Federal Tax Reform is the fact that America has become divided between a growing class of people who pay no income taxes and a shrinking class of people who are bearing the lion’s share of the burden.
Despite the charges of critics that the tax cuts enacted in 2001, 2003 and 2004 favored the “rich,” these cuts actually reduced the tax burden of low- and middle-income taxpayers and shifted the tax burden onto wealthier taxpayers. Tax Foundation economists estimate that for tax year 2004, a record 42.5 million Americans who filed a tax return (one-third of the 131 million returns filed last year) had no tax liability after they took advantage of their credits and deductions. Millions more paid next to nothing.
