CBS: Higher government spending could hamper growth over the next 30 years, the CBO said Thursday

The U.S. economy could face slower economic growth over the next three decades due to weak population gains and increased government spending, the nonpartisan Congressional Budget Office said Thursday.

The CBO's latest long-term budget and economic outlook report, which covers a timeframe that spans 2025 to 2055, projects publicly held debt to reach 156% of gross domestic product, or GDP, in 2055. That's down from the agency's March 2024 long-term budget projection, which said publicly held debt would be equal to a record 166% of American economic activity by 2054.

But that's not necessarily a positive.

The mix of slower population growth and unfettered spending will also lead to weaker economic growth over the next three decades than what the CBO projected last year. Lower birthrates also mean that the United States is becoming more dependent on immigrants working to sustain growth.

"Without immigration, the U.S. population would begin to shrink in 2033," the CBO report states.

The report assumes that all the laws set to expire, including certain provisions of Trump's 2017 tax cuts, will do so. But the White House and Republican lawmakers are seeking to renew those tax cuts as well as add new reductions, such as eliminating taxes on overtime, which the Tax Foundation estimates could cost $4.5 trillion over the next decade.

"As bad as this outlook is, it represents an 'optimistic' scenario, because policymakers are currently considering adding trillions more in tax cut extensions, which would only add to these levels of debt," said Michael A. Peterson, CEO of the economic think tank Peter G. Peterson Foundation, in a statement. 

Extending the tax cuts could double the deficit and push debt to 214% of GDP, he added. "And if interest costs are one percentage point higher than expected, debt would balloon to 250% of GDP, showing just how sensitive our fiscal health is to the unpredictable interest rate landscape," Peterson said.
