Looking back in 1981, Biden said he had been persuaded to evolve by his fellow lawmakers.

“I have been made a believer over the last nine years in the Senate,” he said. The teachings of economists, he continued, had made him reluctant to listen to his Republican colleagues about the dangers of deficit spending, particularly when he was just an impressionable 29-year-old “not too long out of college.” But eventually, he was worn down. “As I listened over the years in this body, I became more and more a believer in balanced budgets,” he said.

Following what he termed an “olive branch” from Reagan — a spending freeze that also raised taxes — he linked arms with two Republican colleagues on the Senate Budget Committee to introduce his own freeze proposal in 1984. Acknowledging it would be labeled “draconian” (“I don’t know how to do anything else than bring it to a screeching, screeching halt,” he said), Biden’s plan cut $239 billion from the deficit over three years, almost $100 billion more than even Reagan’s proposal, and proposed doing it partly by eliminating scheduled increases for Social Security and Medicare beneficiaries. It would, he said, “shock the living devil out of everyone in the US Senate.”
