The last time Dems had a super majority and filibuster proof majority(briefly), we got the second most productive Congress in history. Not to mention the Affordable Care Act.

The 111th Congress was the most productive congress since the 89th Congress.[7] It enacted numerous significant pieces of legislation, including the Lilly Ledbetter Fair Pay Act, the American Recovery and Reinvestment Act, the Patient Protection and Affordable Care Act, the Dodd–Frank Wall Street Reform and Consumer Protection Act, and the New START treaty.

Despite Democrats holding thin majorities in both chambers during a period of intense political polarization, the 117th Congress oversaw the passage of numerous significant bills,[3][4] including the Inflation Reduction Act, American Rescue Plan Act, Infrastructure Investment and Jobs Act, Postal Service Reform Act, Bipartisan Safer Communities Act, CHIPS and Science Act, Honoring Our PACT Act, Electoral Count Reform and Presidential Transition Improvement Act, and Respect for Marriage Act.[4]
