The $1,500 Sandwich: Wendover’s Economics Lesson Breaks Down When the Numbers Meet Reality

Wendover Productions gets the central principle right: producing goods at scale can dramatically reduce unit costs, and transportation influences where factories should operate. But its demonstration of that principle contains arithmetic errors and, more importantly, mistakes an improvised salt-gathering exercise for an industrial production model. The result is an impressive-looking calculation that does not establish what it claims to establish.

The distinction matters. A mathematical illustration of economies of scale is not evidence that a particular manufacturing process is economically viable, nor does multiplying the output of an inefficient process automatically reproduce the economics of an actual factory.

The opening calculation is already wrong

The video says Andy George spent $362.40 producing six ounces of salt, then reports a cost of $52 per ounce.

That is incorrect. The stated expenditure divided by the stated output is $60.40 per ounce. The video's initial figures therefore disagree before the industrial-scale calculations even begin.

The discrepancy matters because the video subsequently uses its initial unit cost to demonstrate the scale of the savings. Its final claim of a 92-fold reduction also does not reconcile with the stated figures: $52 divided by $0.54 is approximately 96.3, while $60.40 divided by $0.54 is approximately 111.9.

These are not competing interpretations of economics. They are arithmetic.
