On September 19, I testified before a House subcommittee on the impacts of Bidenomics—yet it was clear that half the committee members weren’t even listening. That’s disturbing because our lawmakers have played a huge role in making the typical American family about $7,000 poorer in just two and a half years.

Instead of acknowledging the data I presented, the Democrats on the subcommittee only regurgitated their talking points and resorted to espousing falsehoods about the state of the economy. Even if half our leaders won’t listen to the facts, hopefully the American people will, so here’s the truth about Bidenomics.

Under President Joe Biden, the government has spent, borrowed, and created trillions of dollars, and that caused the highest inflation in four decades. This inflation is a real tax on the American people because it transfers wealth from the people to the government. And the size of that transfer has been staggering.

The average American worker today loses more of his hourly earnings through the hidden tax of inflation than in federal income taxes. That means inflation under Mr. Biden has effectively doubled the average American’s federal income tax liability. Nominal pay keeps going up, but real (inflation-adjusted) pay has gone down.

The typical American family with two parents working and with average weekly earnings has seen their weekly pay increase $230 under Biden, but those larger paychecks buy about $100 less. The result is an annual decrease in purchasing power of about $5,100.

Similarly, net household wealth is at a record high today, but only before adjusting for inflation. In real terms, net household wealth is roughly flat since the end of 2020. That means nearly all the trillions of dollars in additional net household wealth have been confiscated by the government under this president through the hidden tax of inflation.

That’s how the government has been financing its massive deficits for the last three years.

To combat the inflation that it helped cause, the Federal Reserve has increased interest rates which have compounded the pain for Americans. Borrowing costs have risen dramatically and are now about $1,800 higher annually for the typical American family. Coupled with their loss in purchasing power, this leaves a family about $7,000 poorer than when Mr. Biden took office.

Yet many people are even worse off than that. If you’re trying to buy a home today, the monthly mortgage payment on a median price home has more than doubled under Mr. Biden. Homeownership affordability is at one of its lowest levels on record, and less than half of American households can qualify for a mortgage. And many who qualify still can’t afford the payments.

The impact of Bidenomics on federal finances has been just as bad, with interest on the federal debt rising at the fastest pace on record. In less than a decade, interest payments will crowd out more than half of existing government spending.

While the Democrats on the subcommittee refused to listen to any facts I presented, nothing I said was about politics, but policy. President Bill Clinton, a Democrat, signed welfare reform and multiple balanced budgets. And the 12 years of low inflation that preceded Mr. Biden were overseen by both a Republican and a Democrat.

The laws of supply and demand are purely apolitical, with both Democrats and Republicans being subjected to them. The sooner today’s Democrats—and some Republicans—realize this, the sooner they can acknowledge the factual outcomes of Bidenomics and hopefully change course.

But if the conduct of the Democrats on the subcommittee before which I testified is any indication, we shouldn’t hold our breath.
