If you want to understand what makes Elizabeth Warren so special in American politics, consider her nervy leadership of the campaign to block President Obama's foolish nomination of one Antonio Weiss to be the top Treasury official in charge of the domestic financial system, including enforcement of the Dodd-Frank Act. For most of his Wall Street career, Weiss has epitomized everything that reeks about financial abuses. As chief of international mergers and acquisitions for Lazard, Weiss orchestrated what are delicately known as "corporate inversions," in which a domestic corporation moves its nominal headquarters offshore, to avoid its U.S. taxes. And that's only the beginning. Many of the other deals orchestrated by Weiss resulted in operating companies being bought and sold by giant conglomerates, where the "savings" and "increased efficiency" came mainly from tax breaks and reduced worker compensation.
