Keynesian economics. At the center of the concept was the Laffer curve, the idea that high tax rates reduce government revenue. Gilder wrote a book extending the ideas of his Visible Man (1978) into the realm of economics, to balance his theory of poverty with a theory of wealth. The book, published as the best-selling Wealth and Poverty in 1981, communicated the ideas of supply-side economics to a wide audience in the United States and the world. Gilder also contributed to the development of supply-side economics when he served as Chairman of the Lehrman Institute's Economic Roundtable, as Program Director for the Manhattan Institute, and as a frequent contributor to Laffer's economic reports and the editorial page of The Wall Street Journal. Technology In the 1990s, he became an evangelist of technology and the Internet. He discussed emerging trends in several books and his newsletter, the Gilder Technology Report. The first mention of the word "Digerati" on USENET occurred in 1992 and referred to an article by Gilder in Upside magazine. His other books include Life After Television, a 1990 book that predicted microchip "telecomputers" connected by fiberoptic cable would make broadcast-model television obsolete. The book was also notable for being published by the Federal Express company and featuring full-page advertisements for that company on every fifth page. Gilder wrote the books Microcosm, about Carver Mead and the CMOS microchip revolution; Telecosm, about the promise of fiber optics; and his latest, The Silicon Eye, about the Foveon X3 sensor, a digital camera imager chip. The book cover of the Silicon Eye reads, "How a Silicon Valley Company Aims to Make All Current Computers, Cameras, and Cell Phones Obsolete." The Foveon sensor has not achieved this goal and has not yet been used in cell phones. Gilder is an investor in private companies and serves as the chairman of the advisory board in Israel-based ASOCS that he discovered during his research for Israel Test. On women and feminism In the early 1970s, Gilder wrote an article in the Ripon Forum defending President Richard Nixon's veto of a day-care bill sponsored by Senator Walter Mondale (D-Minnesota) and Senator Jacob Javits (R-New York). He was fired as editor as a result. To defend himself, he appeared on Firing Line. Gilder moved to New Orleans and worked in the mornings for Ben Toledano, Republican candidate for the United States Senate in 1972 and the
