In Washington, D.C., he rose by virtue of seniority to the rank of Chairman of the House Ways and Means Committee in 1981, just as the Reagan Revolution marginalized many other Democratic politicians. As Chairman of Ways and Means, he played a critical role in formulating tax policy during the Republican administration of Ronald Reagan, including the Economic Recovery Tax Act of 1981, which cut the top federal bracket to 50%, and the Tax Reform Act of 1986, which further lowered it to 28% and reduced the number of brackets to only two. He was also involved in trade policy, as well as reforms of the welfare system, health care and Social Security programs
