(FORTUNE Magazine) – Simplification: that was definitely the name of the game. That Senate Finance Committee tax bill was going to simplify the tax code. The Keeping Up Simplification File, as we have labeled this mound of clippings on the floor, repeatedly makes this point. Why, here is a news story about the President supporting the bill because it ''dramatically simplifies'' the tax code. And here is a clipping, in which the U.S. Chamber of Commerce enthuses over this ''important step toward simplification.'' Elsewhere in our pile, Raymond A. Hay, chairman of LTV, is praising the new ''tax fairness and simplification.'' Deputy Treasury Secretary Dick Darman and White House Spokesperson Larry Speakes are stated on other pieces of newsprint to be all out for the legislation, and they evidently have the same writer as Reagan because they too are impressed by the way the bill ''dramatically simplifies'' things. Yet here is this funny number, which suddenly surfaced on June 6. The number is 1,489. Yes, friends, 1,489 is the number of pages in the document produced by the Finance fellows when they got around to putting their handiwork in legislative form. Does this clipping belong in the Simplification File? That is our complicated question.
