from the article: "The story of the tax break is in many ways the story of U.S. tax policy writ large. Congress enacts a loophole-laden law whose benefits skew toward the ultrarich. Lobbyists defeat efforts to rein it in. Then creative tax specialists at law, accounting and Wall Street firms transform it into something far more generous than what lawmakers had contemplated."
This is so true, and deserves to be more widely known.
