Committee for a Responsible Federal Budget
MacGuineas has served as president of the Committee for a Responsible Federal Budget, a nonpartisan public policy organization dedicated to fiscal issues, since 2003. The Committee has been described as a “budget watchdog” by The Hill . Under her leadership, the Committee grew in stature as it became a prominent voice for tackling rising national debt that is projected to reach record levels as a share of the economy in the years to come. A Roll Call article stated, “the previously obscure organization, a home for former federal budget officials, has been pulled into the spotlight, speaking to what its members and supporters argue is the overriding fiscal issue of the time.” In 2012, she became head of the Campaign to Fix the Debt, a project of the Committee that seeks a comprehensive and bipartisan approach to addressing rising national debt. Business leaders, economists, and budget experts became involved with the Campaign, as well as thousands of grassroots supporters. She has testified before congressional committees on several occasions. A Wall Street Journal piece described her as an “anti-deficit warrior.”
FixUS
MacGuineas is also a founder of FixUS, a project of the Committee for a Responsible Federal Budget. According to its website, “FixUS is a group of Americans united in shared concern over the divided state of our country. We believe that healing these divisions is our highest national priority, and essential to preparing our nation to face the defining challenges of the 21st century.” In April 2019, she wrote in USA Today, along with FixUS Director Mike Murphy, “In many ways our budget deficits and ever-rising debt are a symptom and symbol of the deterioration of our politics... As a nation, we have become incapable of making tough choices or achieving bipartisan compromise. We are focused on the short term at the expense of the long term. And we reward hyper-partisanship over making progress on behalf of the American people.” An op-ed by MacGuineas in July 2019 in The Washington Post struck a similar note, “The dysfunctional budget process, the untenable debt situation and the inability to solve the most glaring budget problems — from a tax base riddled with ineffective loopholes, to Social Security, to the need to reform the debt ceiling — reflect the larger corrosive situation of today’s broken governance system.”
