FILE - In this Feb. 20, 1985 file photo, British Prime Minister Margaret Thatcher turns to look at the crush of photographers in the Oval Office as President Reagan laughs during a photo session at the White House in Washington. It's been most of three decades since debate over "supply-side" economic policies was at the center of U.S. politics. But the conservative economic ideas are in the news again, after the death of Thatcher and a scathing attack unleashed last week by Reagan's budget director on years of economic decision-making, including by his former boss.
