Mark Weinberger didn't serve long as George W. Bush's assistant treasury secretary for tax policy, but until he retired last April, he was a man with a mission. Before and since -- and apparently during -- his brief stint at the U.S. Department of the Treasury, Weinberger worked at Ernst & Young, the outspokenly unpatriotic accounting giant [See Robert S. McIntyre, "Putting Profits over Patriotism," TAP, March 25, 2002.]. He was sent to the Treasury to accomplish one key goal: Undermine a law requiring corporations seeking a tax credit for research and experimentation to engage in, well, actual research and experimentation.
