From the summary:
In this testimony Burman discusses the issues of tax fairness, the 2001 to 2006 tax cuts, and the individual alternative minimum tax. Burman argues that while the federal tax system mitigates economic inequality, the recent tax cuts have disproportionately benefited those at the top, while also increasing the number of people potentially subject to the AMT. He concludes with a brief discussion of how to fix the AMT in a fiscally responsible manner.
