Let me assure you as a purebred Yankee that Marmite is indeed superior to Vegemite in almost every possible respect. At any rate, remember this?
After several years of fairly decent free market reforms, let's hope we don't (or do, depending on your preferences) see a repeat performance from someone equally talented, but living in Auckland. Let's also hope that in the event prices rise, it's because prices contain information. In this case, the information is that there won't be any Marmite until the factory is back on its feet. Asserting central control over prices in response to a supply shock disrupts the signals that allow unexpectedly scarce goods to be allocated to their highest value use.
Do me proud, NZ.
