The White House is preparing to issue a $6 trillion budget proposal that would put the US at its highest planned spending levels since World War II, according to a report.

The budget is expected to be released Friday as President Biden’s plan to hike taxes to finance social spending and broadly defined infrastructure faces resistance in Congress.

The $6 trillion budget for fiscal 2022 is an aspirational document and is unlikely to be ratified without significant changes.

The budget is so large because it includes part of the roughly $4 trillion in spending for Biden’s proposed infrastructure and “families” plans, the New York Times reports.

If adopted, the plan would put the US annual budget deficit at $1.3 trillion per year for the next decade, according to the report, with the budget scaling up to $8.2 trillion by 2031.

The government would spend approximately one-quarter of US economic output over the next decade and by 2024 could see the highest-ever national debt as a proportion of the economy.

The budget reportedly doesn’t include any new major policy proposals.

In a blow to left-wing Democrats, it isn’t expected to include proposed funding for a “public option” for health insurance that would compete with private policies, but it is expected to call for a public option and for lowering the Medicare age to 60, from 65.

But there’s no guarantee the budget will be adopted due to stiff Republican opposition to tax hikes on businesses, higher incomes and investments and concern from centrist Democrats about the scale of spending and the omission of certain items.

The plan comes amid reports of rising inflation on the heels of Biden’s $1.9 trillion COVID-19 stimulus bill, which passed in March with no Republican votes.

A prominent Democratic economist, Larry Summers, warned Wednesday that Biden risks sending the economy into chaos with inflation.

“We’re taking very substantial risks on the inflation side,” said Summers, who was a top White House economic adviser to Presidents Bill Clinton and Barack Obama.

“I think policy is rather overdoing it. The sense of serenity and complacency being projected by the economic policymakers, that this is all something that can easily be managed, is misplaced,” Summers said.

Biden’s two mammoth spending plans currently pending in Congress include his infrastructure bill, which he originally pitched at $2.3 trillion, with $400 billion planned for home and community health care, $174 billion for electric vehicle subsidies, $115 billion for roads and bridges, $111 billion for water systems, $100 billion for school construction and $100 billion for broadband internet, among other items.

A Senate Republican counteroffer on infrastructure, unveiled Thursday, came in at $928 billion. Republicans object to social spending in Biden’s plan, but also differ on how to pay for it.

The Times reports that Biden’s budget would put the US at its highest planned level of spending as a percentage of the economy since World War II, though overall spending was higher in 2020 and 2021 due to emergency pandemic packages.

If they maintain unity, Democrats are able to ram Biden’s massive infrastructure plan through Congress — plus the complimentary $1.8 billion “families” plan — without any Republican votes under budget reconciliation rules that bypass the usual 60 votes needed in the Senate.

The “families” plan calls for $511 billion for education, including universal preschool for 3- and 4-year-olds and free community college, $225 billion for child care, including a subsidy that caps expenses at 7 percent of income, and $225 billion to subsidize 12 weeks of paid parental and sick leave and $45 billion more for food stamps and school food programs. It contains $800 billion in tax credits, including to make the more generous child tax credit permanent and award $200 billion to Obamacare users.

In April, the White House previewed significant elements of the fiscal 2022 budget, including a 16 percent jump in domestic agency spending and a 1.7 percent bump for the military.

The annual budget includes about $3 trillion in mandatory spending on entitlements like Social Security and Medicare and interest on the national debt.

Budget details previewed in April included $861 million to invest in Central America to address the forces driving people to migrate to the United States and an additional $345 million to immigration services to resolve delays in years-long naturalization and asylum cases. The budget proposes funds to hire 100 new immigration judges.

Other specific budget items include putting $2.1 billion toward the Justice Department to address “the gun violence public health crisis plaguing communities across the Nation,” according to an April fact sheet. That would be an increase of $232 million from 2021. It also seeks a $1 billion boost to the IRS — for a total $13.2 billion — to help catch tax cheats.

Democrats face internal divisions, however, on Biden’s big-ticket legislative proposals, increasing the appeal of compromise that could shrink the overall size of the spending.

In the House, where Democrats hold an eight-seat advantage, a trio of New York-area legislators led by Rep. Tom Suozzi (D-NY) say they won’t agree to any changes in the tax code unless the $10,000 “SALT cap” is eliminated. The cap since 2017 has limited the amount of state and local taxes that residents of high-tax jurisdictions like New York can deduct before paying federal taxes, and its repeal wasn’t in Biden’s new proposals.

And in the Senate, Sen. Joe Manchin (D-W.Va.) whose vote alone could derail the infrastructure and “families” bills, said he’s “very uncomfortable” with the amount of spending being proposed.

The White House Office of Management and Budget did not immediately respond to a request for comment.
