What has been the main argument over recent efforts to replace the personal income tax with a value-added tax?

What will be an ideal response?

Opposition to the VAT focuses on its inherent regressivity. It can be argued that the U.S. individual income tax already exempts much of saving because employer contributions to pension plans and increases in accumulated equity in private homes are not taxed. Opponents also argue that a huge new revenue source like the VAT might tempt the government to raise taxes.
