Nobody wants to pay for Biden’s build-everything plan

President Biden’s $2 trillion plan to build and revamp everything from roads to bridges to schools to factories to broadband would benefit businesses and workers everywhere. Infrastructure improvements make the whole country more productive and efficient. Demand rises. Companies make more, hire more and pay more. Growth perks up. Mostly everybody ends up better off.

Just don’t ask anybody to pay for this economic wonder. The nation’s biggest business groups all support robust infrastructure spending, but as Biden rolled out his big plan on March 31, they all insisted somebody else should foot the bill. Biden wants to fund it by raising the corporate tax rate from 21% to 28%. Nope, say America’s businesses. Find another way.

The Business Roundtable, US Chamber of Commerce and National Association of Manufacturers all issued statements supporting the goal of Biden’s infrastructure plan on the same day Biden began releasing the details. And they all said raising business taxes would be a counterproductive way of funding it. Instead, they want “user fees” to be the source of funding. That means tolls for roads, bridges and tunnels, and other types of charges for those actually benefiting from the new infrastructure.

That’s not a bad approach, in principle. User fees in the form of a gasoline tax were the main funding source for the national highways system President Eisenhower signed into law in 1956, perhaps the most important US infrastructure program ever. That arrangement worked for decades.

But the federal gas tax has been stuck at 18.4 cents per gallon since 1993, with inflation and improving fuel efficiency greatly eroding its power as a transportation funding mechanism. By one estimate, the purchasing power of that tax revenue has plunged by 64% since 1993. This coincides with growing Republican hostility toward tax increases for any reason at all, which didn't always block new taxes. President Ronald Reagan, the archetypal Republican, signed a gas-tax increase into law in 1983, and his successor, fellow Republican George H. W. Bush signed another one into law in 1990.

But since the last hike under President Clinton in 1993, Republicans who controlled one or both houses of Congress most of the time have squelched any new gas-tax funding for transportation. Part of the problem has been declining income tax rates for the wealthiest Americans, with the top marginal rate falling from 50% in 1986 to 37% today. Business taxes have fallen too, with the top corporate rate falling from 46% in 1986 to 21% today. Politicians can’t plausibly cut taxes on the wealthy but raise gasoline taxes on ordinary people.
