House Speaker Mike Johnson (R-La.) is feeling pretty good about the American worker these days. In a Labor Day message on X, he declared that "The American worker is WINNING again!" and credited Republican policies for giving hardworking folks more opportunities and letting them keep more of their own money.

Johnson's post was a highlight reel of economic wins: "Bigger paychecks," "No Tax on Tips or Overtime," "ONE MILLION private-sector jobs added," and "TRILLIONS in investment coming into America." He wrapped it all up with a patriotic bow: "A MADE IN AMERICA comeback." And just in case you missed the point, he added, "American manufacturing is BOOMING."

Now, is the manufacturing sector actually booming? Well, the data tells a story that's mostly supportive, if a bit nuanced. U.S. manufacturing activity expanded for the eighth consecutive month in August, according to the ISM Manufacturing PMI. The index slipped to 54.6% from 55.6% in July, which is still firmly in growth territory. New orders, backlogs, and imports weakened a bit, but production stayed strong. Prices, however, remained elevated at 71.1%, which is a number that might make you wince if you're shopping for anything made of metal or plastic.

The National Association of Manufacturers adds some heft to the "booming" claim: manufacturers contributed $3 trillion at an annual rate to the U.S. economy in the first quarter of 2026, and the sector employed nearly 12.6 million workers. That's a lot of people making things.

Treasury Secretary Scott Bessent is also on the manufacturing revival bandwagon. Last week, he argued that Trump's "America First" policies are driving a renaissance by boosting construction and factory investment. He claimed construction jobs in factory-related sectors are growing "10x faster than under Biden" and said these policies are creating the conditions for "greater investment, stronger supply chains, and more opportunities for wage growth." His punchline: "This construction renaissance will continue to drive our manufacturing renaissance."

But not everyone is popping champagne. Some economists are looking at the bond market and seeing storm clouds. On Tuesday, economist Robin Brooks warned that Treasury yields are rising despite weaker U.S. economic data, suggesting the market's underlying dynamic is "worse than meets the eye." His take: investors are increasingly focused on the U.S. budget deficit, "regardless of what data surprises are doing."

Investor Peter Schiff goes even further, calling it "ridiculous" to dismiss factors like "increased inflation expectations, a loss of confidence in U.S. fiscal policy, declining Fed credibility," and de-dollarization as reasons for the yield spike. In other words, the bond market might be voting on fiscal policy, not just the economy.

Meanwhile, the broader jobs picture remains solid. The U.S. economy added 162,000 jobs in August, blowing past expectations of 56,000. Unemployment held steady at 4.1%. Food services and local government education led the gains, while the information sector shed 23,000 jobs. Average hourly earnings rose 0.3% from the previous month.

So, is it all sunshine and booming factories? The political spin machine is running at full tilt, and the data does show a resilient economy with a manufacturing sector that's been expanding for eight months straight. But the bond market's whispers about deficits and fiscal credibility are worth listening to. After all, you can have a booming factory floor and still worry about the foundation the building sits on.
