WASHINGTON - President Joe Biden was scheduled to tour the Lehigh Valley operations facility for Mack Trucks on Wednesday, a chance to touch base with the plant’s 2,500 workers, a majority of whom are unionized. Biden has made manufacturing jobs a priority, and Democrats’ political future next year might hinge on whether he succeeds in reinvigorating a sector that has steadily lost jobs for more than four decades.

The administration is championing a $973 billion infrastructure package, $52 billion for computer chip production, sweeping investments in clean energy and the use of government procurement contracts to create factory jobs. Biden will be briefed Wednesday on Mack’s electric garbage trucks.

“This is all part of his effort to lift up and talk about his Buy American agenda as well as the infrastructure package,” White House press secretary Jen Psaki said Tuesday in previewing the visit.

The president won Lehigh County in the 2020 election, but he is facing the perpetual challenge of past administrations to revive a manufacturing sector at the heart of American identity. Failure to bring back manufacturing jobs could further hurt already ailing factory towns across the country and possibly imperil Democrats’ chances in the 2022 midterm elections.

Pennsylvania Sen. Pat Toomey, a Republican, said Biden should siphon off unspent money from his $1.9 trillion coronavirus relief package to cover the investments in infrastructure, instead of relying on tax increases and other revenue raisers to do so.

“Hopefully, he will use his visit to learn about the real, physical infrastructure needs of Pennsylvanians - and the huge sums of unused ‘COVID’ funds which should pay for that infrastructure,” Toomey said in a statement.

Deindustrialization has been a thorny problem for Democrats seeking voters during elections.

Layoffs of white factory workers led communities to vote for Republican challengers and turn against Democratic incumbents, according to a 2021 research paper by McGill University’s Leonardo Baccini and Georgetown University’s Stephen Weymouth. They found a connection between deindustrialization and greater racial division as white voters interpreted the layoffs as a loss of social status.

Areas with more factory layoffs also became more pessimistic about the entire economy. The trends documented in the research were most pronounced in 2016, when Donald Trump won the White House while emphasizing blue-collar identity and racial differences.

One challenge for Democrats is that they’re not being forced to deal with the most recent manufacturing job losses, but layoffs that began decades ago.

American made

The Biden administration is separately trying to help domestic manufacturers by proposing Wednesday to increase the amount of American-made goods being purchased by the federal government.

Administration officials who insisted on anonymity to discuss the measures said they’re proposing that any products bought by the government must have 60% of the value of their component parts manufactured in the United States. The proposal would gradually increase that figure to 75% by 2029, significantly higher than the 55% threshold under current law.

Manufacturing has improved since the depths of more than a year ago during the coronavirus pandemic-induced recession. Labor Department data show that factories have regained about two-thirds of the 1.4 million manufacturing jobs lost because of the outbreak. Factory output as tracked by the Federal Reserve is just below its pre-pandemic levels.

Auto challenges

But the manufacturing sector - especially autos - is facing serious challenges.

Automakers are limited by a global shortage of computer chips. Without the chips that are needed for a modern vehicle, the production of cars and trucks has dropped from an annual pace of 10.79 million at the end of last year to 8.91 million in June, a decline of nearly 18% as measured by the Fed.

Analysts at IHS Market estimate that the supply of semiconductors will only stabilize and recover in the second half of 2022, right as the midterm races become more intense.

The impact of the chip shortage can trickle through the rest of the economy. Used vehicle prices have shot up 45.2% from a year ago, since there are not enough newly built cars and trucks available.

The administration has been proactive in trying to address the problem, advocating for a bill designed to increase semiconductor production in the United States in ways that would also help other manufacturing sectors.
