If this is the case, why has it not happened yet?

I'm not refuting that, I'm only saying that in the context of public health, cheaper corn syrup being subsidized doesn't make a difference when it comes to consumer behavior. That doesn't mean that producers are going to be dumb and buy sugar when corn syrup is so much cheaper. Consumers aren't going to stop drinking coke because it costs 1% more, but the beancounters at coca cola are certainly going to care if they're spending 50% (made up number) more on sweeteners if they don't have to.

The delta does not matter to the consumer. They might pay <5% more, hardly a dent in demand would follow. The producer has a small profit margin so it does matter for them, since production and logistics cost a lot.

> If there's only 10 cents worth of sugar in a 2L bottle of coke, switching to sugar is unlikely to change the consumers buying habits.

It matters enough that it determines where things get manufactured though.

> There are two prices for sugar: the price you pay in the U.S., and the price you pay almost everywhere else in the world.

> The price in the U.S. is about 15 cents a pound higher than the price in the rest of the world. That costs Spangler Candy an additional $3 million a year.

> The higher U.S. sugar price is spelled out in U.S. law. You can find it right here, in the latest version of the farm bill, which says the U.S. government shall guarantee a minimum price for sugar that is not to drop below 22.9 cents per pound.

While true, if this was something we really cared about, it's easily solved with tariffs. This is an actual job for tariffs.

Counterargument: the UK's Soft Drinks Industry Levy.

In 2018, the British government introduced a tax on soft drinks with a sugar content of more than 50g per litre. The tax isn't particularly onerous, at 18p or 24p (22¢ or 29¢) per litre depending on the sugar content. The industry response was immediate - the majority of drinks were reformulated to reduce their sugar content to below the threshold, which is precisely what the government intended. Although initially controversial, the levy is now regarded as a clear victory for public health, with no significant economic impact on industry.

Even if the purchasing habits of consumers are price-inelastic, the decisions of manufacturers most certainly aren't.

It's certainly made me buy less UK Dr Pepper in Australia (I find artificial sweeteners generally unpleasant). Many places down under that sell it are now stocking US Dr Pepper instead, which suggests it sells rather better.

I avoid the reduced-sugar ones. Actually these days I tend to buy the little miniature 150ml Coca-Cola cans. Original recipe but only 15g sugar as there's just less of it. Portion size is just as important as concentration!

It completely killed my soft drink buying habits. So it was either a success or failure depending on how you look at it.

I can’t stand the reformulated sweetened drinks. The flavour profile and aftertaste is completely different. I wasn’t a huge consumer of soft drinks to start with, but now I consume absolutely zero.

This is a win from a public health standpoint also.

I don't think this had the desired effect for me (or maybe it did). When I have a coke, or other soft drink it's generally because I want the sugar and caffeine, for instance part way through a long drive or during a night out. Generally I drink water, tea and a little coffee. I don't really want to be eating/drinking any artificial sweeteners. I have a hunch that this is not good for you and adjusts your taste to wanting more sweet things, so I tend to avoid. Regular Coca Cola still tastes ok, but now all promotions tend to be on sweetened drinks. Drinks such as Irn Bru have been ruined, as there is now no full sugar version available.

Unfortunately they didn't take the opportunity to reduce the sweetness. Here in Norway I can buy flavoured water without any sweeteners at all, neither sugar nor artificial. But when I visit the UK all I can find is either plain water or something sickly sweet.

The industry is already a step ahead on this stuff. I'm sure they have reams of market research that say "If a tax appears that causes Coke to be $1.49 per litre and Diet Coke is $1.29, there's a nontrivial amount of customers who will skip the soda rather than switching to the existing diet brand." So they need a product they CAN slide in if the shoe drops.

They brought out "half-sugar" sodas about 20 years ago (Coke C2), but they hit the market with a thud. I suspect that the recent "Zero Sugar" brands are intended to fill the same spot. Notice how the branding is much closer to the sugared brand than the diet brands, and TBF, they're a lot more comparable taste-wise to the sugared versions than Tab or Diet Coke ever were.

There's little case for introducing these products if it's primarily going to cannibalize their existing brands and consume already limited shelf space, unless there's some long-term appeal in it. But if there's a sugar tax, or some dramatic economic fallout that makes sugar ahistorically expensive, watch as the default position on the vending machine suddenly switches to suddenly Coke Zero.

On the other hand, it's demonstrably proven that food producers will switch from sugar to corn syrup rather than pay extra for cane sugar, so consumers are deprived of a choice.

What good would that choice do them? You can choose to buy products made with sucrose, but ceteris paribus, the sucrose product won't be healthier. This is a little like asking whether consumers can choose to buy less-sweetened food, and, of course they can.
