"The economy faces a slump deeper than the Great Depression and a growing deficit threatens the credit of the United States itself, former Goldman Sachs chairman John Whitehead, said at the Reuters Global Finance Summit on Wednesday.
Whitehead, who helped make Goldman a top-tier Wall Street firm and led its international expansion, left in 1984 to become a deputy secretary of state under Ronald Reagan.
He warned that the country's record deficit is poised to balloon as the public calls on government for more support.
"Before I go to sleep at night, I wonder if tomorrow is the day Moody's and S&P will announce a downgrade of U.S. government bonds," he said. "Eventually U.S. government bonds would no longer be the triple-A credit that they've always been."
Large deficits can weaken the country's credit and increase its borrowing costs, which already constitute a significant part of funding to cover expenses. Whitehead said it could take "several years" for the current problems to be resolved.
Whitehead said he is speaking out on this topic because he is concerned no lawmakers are against these new spending programs and none will stand up and call for higher taxes.
"I just want to get people thinking about this, and to realize this is a road to disaster," said Whitehead. "I've always been a positive person and optimistic, but I don't see a solution here."
