Brian Albrecht dismantles a seductive but dangerous economic fallacy that has recently resurfaced in public discourse: the idea that swapping high income taxes for low tariff rates is a net win for the economy. While the math looks clean on a spreadsheet, Albrecht argues that this comparison ignores the fundamental mechanics of how different taxes distort human behavior. For busy leaders trying to parse the real cost of trade policy, this piece cuts through the noise to reveal why a 2.5% tariff can be far more damaging than a 40% income tax.
The Trap of Nominal Rates
The piece begins by addressing a claim made by John Lott, who suggested that because average tariff rates are tiny compared to income tax rates, shifting the burden to imports would reduce the overall economic burden. Albrecht immediately identifies the flaw in this logic, noting that "No one corrected him on this. Even economists who pushed back on Lott missed it or ignored it." The danger here is that the argument sounds plausible to non-specialists because it relies on a single, true principle applied to the wrong context.
Albrecht explains that while it is true that deadweight loss—the economic value destroyed by a tax—increases with the square of the tax rate, this rule only holds within a single market. He writes, "This principle compares a fixed market with a fixed demand and supply curve. This relationship only holds within a given tax base." The error in Lott's logic is treating all tax bases as identical, when in reality, the responsiveness of buyers and sellers varies wildly between markets.
"Elasticities destroy any attempt to compare tax rates across different bases and make Lott's whole construction nonsense."
This is the crux of the argument. A tax on land, where supply is fixed, creates zero distortion regardless of the rate. A tax on imports, where supply and demand are highly responsive, creates massive inefficiencies even at low rates. Albrecht points out that imports are "very elastic," citing estimates that put the long-run elasticity at 14, implying that "a huge deadweight loss" is generated even by small tariffs. The nominal rate is a red herring; the behavioral response is what matters.
The Compound Effect of Layered Taxes
The analysis deepens as Albrecht moves beyond isolated markets to show how taxes interact. He argues that income taxes and tariffs do not operate in a vacuum; they stack on top of one another, compounding the distortion on workers and consumers. He illustrates this with a simple budget constraint: if you earn a wage, pay income tax, and then face higher prices due to tariffs, the total "wedge" between your labor and your consumption is the sum of both distortions.
He demonstrates that a 10% income tax is economically identical to an 11.1% consumption tax, proving that "you can't look at the nominal rates and conclude that one tax is lower than the other." When a tariff is added to an existing income tax, it doesn't just add a small cost; it creates a specific, targeted wedge that distorts choices between domestic and imported goods. Albrecht writes, "The tariff creates a much bigger wedge specifically on imported goods, which distorts your choice between domestic and imported goods even when both are equally efficient in production."
Critics might argue that tariffs can serve strategic goals beyond revenue, such as protecting nascent industries or national security. While valid, Albrecht's point remains that as a revenue-raising mechanism, they are mathematically inefficient compared to broad-based taxes. The narrow base of tariffs means that to raise meaningful revenue, the rates must be astronomically high, leading to "astronomical rates that create massive distortions in consumption patterns."
"The narrow base means you need a much higher rate to raise equivalent revenue."
This logic exposes why replacing income tax with tariffs is a false economy. Because imports make up only a small fraction of total consumption—roughly 10% in the US—a tariff must be applied at a rate ten times higher than a general consumption tax to generate the same revenue. Albrecht notes that this is the same logic that would apply to a sugar tax: "To raise meaningful revenue, you need astronomical rates that create massive distortions... It may even be impossible for reasons related to the Laffer curve."
The Mathematical Reality
Albrecht concludes by grounding these intuitions in explicit math, showing how the total tax wedge depends on the interaction of income and consumption taxes. He derives a formula where the total distortion is not simply the sum of the rates, but a function of how they compound. "The consumption tax and income taxes aren't unique things that we can isolate," he writes. "They compound."
The result is a clear verdict on the proposed policy shift. Replacing a broad income tax with a narrow tariff base would not lower the economic burden; it would concentrate the distortion on a small slice of the economy, forcing consumers to make inefficient choices. Albrecht's model shows that a 100% income tax is equivalent to an infinite consumption tax, highlighting the absurdity of comparing rates across different bases without accounting for the underlying economic structure.
"You can't compare tax rates across different bases without accounting for how responsive behavior is to each tax."
Bottom Line
Albrecht's strongest contribution is exposing the fallacy of comparing nominal tax rates across different economic bases, a mistake that has confused even seasoned observers. The argument's vulnerability lies in its strict focus on efficiency; it does not address the political or strategic motivations that often drive tariff policy, such as geopolitical leverage or domestic manufacturing goals. However, for anyone evaluating the economic cost of trade policy, the takeaway is unambiguous: low nominal rates on narrow bases can create far higher economic costs than high rates on broad bases.
