When Hasan Minhaj asked Nobel Prize-winning economist Paul Krugman whether voters should believe politicians who promise to “bring prices down,” Krugman was blunt.

“Any politician who promises to bring prices way down is either ignorant or lying, or both,” he said on Minhaj’s podcast (1).

It’s a blunt warning aimed squarely at the kind of sweeping affordability pledge Donald Trump has made central to his political brand.

What Krugman is really saying about prices

In the Minhaj interview, Krugman walks through a basic but often-misunderstood point: prices rarely go down — and usually shouldn’t.

He notes that outside of rare and painful episodes, such as the Great Depression, countries like the U.S. experience inflation, not deflation. Central banks, including the Federal Reserve, deliberately target a low, positive inflation rate of about 2% a year (2). The economy tends to function better with slowly rising prices than with flat or falling prices.

Deflation, Krugman reminds viewers, is “a terrible thing”. It’s associated with deep slumps, debt crises and lost decades.

Crucially, the Fed steers the overall price level. A committee of central bankers sets interest rates and manages the money supply largely independent of the White House.

When a candidate promises to “rapidly drive prices down” everywhere from groceries to homes, Krugman argues they’re either oversimplifying something they don’t understand, or banking on the fact that voters don’t.

Trump’s big promises vs. stubborn bills

Congressman Lloyd Doggett’s “Trump’s Economic Promises Timeline” (3) collects just how far Trump has gone on affordability rhetoric.

Among the highlights:

Once back in office, Trump largely shelved the “make America affordable again” slogan — until recent elections (7), where Democrats over-performed, and affordability emerged as a top issue.

The White House is trying to pivot. According to a recent NPR report (8), Trump has resumed promising to “lower the cost of living” and will travel across the country to tout his plan. Polls show (9) voters blame his policy for making the economy worse.

The numbers help explain why voters are unconvinced. Inflation has run around 3% this year (10). It’s far from the double-digit spikes of the 1970s, but still enough to keep everyday prices marching higher.

Some items are cheaper than when Trump returned to office, but others — such as coffee and ground beef — remain significantly more expensive (11).

What households can actually do about affordability?

If sweeping political promises are unlikely to deliver cheap groceries and rent, what can Americans do to protect themselves?

Economists and financial planners tend to come back to a few practical themes:

In an economy built around steady inflation, the most realistic path is to find ways to keep your income, savings and debt management ahead of the slow, relentless rise.
