We need a new generation of leadership in Washington to move the conversation around Social Security and Medicare away from privatization and towards expansion. Social Security is the most successful public program in our nation's history, lifting millions of seniors out of poverty. Our seniors have done their part, and we need to do ours to support them, by expanding benefits and enhancing retirement security for millions of Americans. Lifting the tax cap for the wealthiest Americans would ensure Social Security's solvency for an additional 30 years and give us the opportunity to expand benefits for seniors who need it.
