President Joe Biden's $1.9 trillion coronavirus relief package is the "right size" to confront the economic effects of the pandemic, Treasury Secretary Janet Yellen said Sunday on ABC's "This Week."
"It's the right size to address the very significant problem that we have," she told "This Week" Anchor George Stephanopoulos. "We need to defeat the pandemic. This package really does that."
"There's enough support in this package to relieve suffering and to get the economy quickly back on track. I'm hopeful that, if we defeat the pandemic, that we can have the economy back near full employment next year. And I think this is the package we need to do that," Yellen added.
It includes provisions that direct relief payments and federal unemployment aid to Americans, gives schools more money to help with reopening and aims to help speed up coronavirus testing and vaccination efforts. Additionally, the bill includes resources for small businesses, housing and food aid, changes to the tax code and the most aggressive expansion of the Affordable Care Act since the health care law's passage.
While the Pew Research Center reported that around 70% of the country supports the bill, some of its critics of the package -- including former Democratic Secretary of the Treasury Larry Summers -- have argued that its historic price tag could balloon the national debt and lead to higher rates of inflation.
Stephanopoulos pressed Yellen about the inflation concerns, amidst recent federal spending.
"If we get back to full employment, could we see inflation surge? How big a problem is that?" he asked the treasury secretary.
"The most significant risk we face is a workforce that is scarred by a long period of unemployment. People being out of work, not able to find jobs can have a permanent effect on their well-being. I think that's the most significant risk," Yellen said. "Is there a risk of inflation? I think there's a small risk. And I think it's manageable."
"I don't think it's a significant risk. And if it materializes, we will certainly monitor for it. But we have tools to address it," she added.
In 2017, Yellen testified that long-term budget projections "should keep people awake at night." With the Congressional Budget Office projecting that the federal debt will exceed the gross domestic product for the first time since World War II, Stephanopoulos asked Yellen Sunday, "are you getting any sleep?"
"I am getting sleep," Yellen responded. "My views have changed somewhat about fiscal sustainability, in part, because what we've seen all around the world is a trend toward very low interest rates. Interest rates in the United States are much lower than they were in past decades, and you see that in all developed countries around the world, and it reflects structural trends that are not going to disappear soon."
"In the longer run, we need to get deficits under control to make sure that our fiscal situation is sustainable," she added.
"President Biden has put forward a number of proposals. He hasn't proposed a wealth tax, but he has proposed that corporations and wealthy individuals should pay more in order to meet the needs of the economy, the spending we need to do, and over time I expect that we will be putting forth proposals to get deficits under control," Yellen said.
When Stephanopoulos challenged Yellen on if that meant the administration would not implement the tax, she responded, "that's something that we haven't decided yet."
