Gibbons, Hon. Sam, testimony (06/08/95) in Hearings before Committee on Ways and Means, publ. in “Replacing the Federal Income Tax,” USGPO, 1996

“The current income tax is an impediment to maximum competitiveness of American companies in international markets.  The income tax simply has not kept up with the many changes that have occurred in the global marketplace.  The current system penalizes exports because under General Agreement on Tariffs and Trade GATT), only indirect taxes, such as a VAT, can be adjusted at the border.  Income taxes cannot be removed from the price of goods when they cross the border to be exported.  I believe that a border-adjustable tax system would promote the competitiveness of American companies and invigorate American exports,” p. 467
