>Unless you think production levels would fall to pathetic levels on the global stage, and that this production-level is essential, I don't see why not.

A few reasons: 1) again, it's partly a national security issue. Under crisis, "global supply" is a concern; just ask Germany after trying to turn away from Russian fuel supply 2) Infrastructure has a relatively large lead time; we can't just ramp up production on a whim. 3) It's odd that you point to global supply as the rationale while simultaneously advocating the largest global supplier severely reduce production. Again, that feels like circular logic. Ie "The US doesn't need to produce ethanol because the world has so much ethanol production." No, the world has so much ethanol production because the US produces a disproportionate amount. Remove the latter and the argument doesn't hold.

I don't think we disagree that making food more expensive can change eating habits. I think we disagree on the most effective vehicle for that.

Look at it this way: we both seem to agree that calories are the problem. Your argument hinges on sweeteners being a proxy for calories, and HFCS being a proxy for sweeteners, and agricultural corn being a proxy for HFCS. You're targeting something that is three levels of abstraction away from what you actually care about. My position is that it makes more sense to target what you're actually after: calories.

If your stance is getting rid of corn subsidies is administratively simple compared to targeting calories, I think I disagree mainly because of the administrative burden of all the other effects we've discussed.

I don't disagree that deterrence is part of an overall strategy. I'm simply pointing out that one should be wary of the tradeoffs. Policy is about prioritizing, and IMO there are likely more pragmatic approaches with less tradeoffs that need to be managed.

I'm not convinced of the strategic importance of ethanol in the grand scheme; the US produces more of it because the subsidy creates that incentive. Incentive structures can change, entrenchment just makes it less politically viable.

It's not abstracted away as healthy eating is concerned. Overconsumption is downstream.

You haven't elucidated how you'd merely target calories through policy, but leaving that aside, a) by default people do not count calories nor would they as a measure to protect against weight-gain, b) it's redundant given a whole-foods diet, no one becomes obese from too much broccoli, chicken breast and lentils, c) for those looking to lose weight, mere calorie counting absent leveraging satiating foods and eschewing junk is woefully ineffective in practice, because of lack of sustainability. Dieters typically do lose some weight, then gain it back. Not only is it difficult to adhere to, it's difficult to eyeball calories on a plate, particularly when they're processed foods, such that they'd have to weigh everything on a scale indefinitely.

Encouraging healthier eating patterns solves several problems at once. It protects against overconsumption, and against disease, which would lessen a burden on the healthcare system. That seems quite pragmatic to me. What's at stake is certain corporations stand to make less money, and corn farmers sell less.

Whether through change in diet patterns or "just eating less" as you might posit, if on the national scale people did end up consuming fewer calories and lose weight, then they'd more than likely consume less sugar/HFCS. The end result is still that a healthier populace == selling less corn. We can't discount any and all policy on the conceit that inconveniencing corn farmers is not acceptable.

Yes, that's the intent. Whenever you subsidize something, you get more of it. If you're looking for strategic rationale, the US relies much more on gasoline than, say, the EU. Couple that with the fact that US strategic oil reserves are at the lowest levels in 40 years, that only leaves about a month of fuel in the reserve at current usage. Meaning, there is a strategic need to have the infrastructure in place to supplement fuel supply if needed. Even if we don't need it now, the lead time for building out infrastructure is long enough that is makes sense to have slack capacity in place now.

>It's not abstracted away as healthy eating is concerned. Overconsumption is downstream.

Corn subsidies are abstracted away. They're related, but not directly considering the other uses of corn. Irrespective of that point, I think we may have lost the thread here. We don't seem to disagree on the central premise that overconsumption of calories is the root issue. The original claim was that a sugar tax would help remedy this issue. The counter-claim was that removing corn subsidies would be a better approach than a sugar tax.

My point is that the counter-claim is lacking nuance, and ignores all the second order effects. I'm not against removing subsidies, but I would want someone to acknowledge how they would mitigate the negative knock-on effects. What you've presented is a bit hand-wavy for my taste, implying we can just swap this crop for that and ignore concerns related to strategic fuel, agricultural stability, and costs. In the context of all those secondary and tertiary impacts, it seems like a direct tax (like a sugar tax) is preferential. I probably wouldn't limit it to just a sugar tax though, and would look to target other food that leads to overconsumption (including those that aren't disproportionately affecting lower socio-economic groups), and ideally making healthier choices less expensive if we're making the others more costly.

My point is that every approach has second-order effects, there's no free lunch. If you pick one approach, then you're dealing with the externalities.

> In the context of all those secondary and tertiary impacts, it seems like a direct tax (like a sugar tax) is preferential

Not to voters. Taxes are unpopular, ending a subsidy to a small powerful cohort would be relatively more popular (in terms of messaging I mean, the end result would still be that consumers pay more for sugar, but of course the govt spending less frees up spending for other things). However, farmer support is right-coded which would lead to opposition by right-wing pundits and media.

It's a toss-up. A tax could be effective, but I don't agree that it's necessarily more viable or palatable. It's probably less-so. Hence I would pitch ending or curbing the subsidy.

[bumby]

We agree that it's always about tradeoffs. I just think there are probably more complex and less transparent (and potentially negative) tradeoffs with ending subsidies if the goal is reducing obesity. It doesn't mean subsidies are good, but just that they are more loosely aligned with obesity than you let on.

I just don't see how it's a more effective strategy given the fact that it's a much more complicated apparatus to do the same thing (raise prices on food). Your position seems to be, stated differently, that higher prices lead to a deterrent to overconsumption and that reducing subsidies is the best way to increase prices. Logically, I can’t find a way that is a better mechanism than affecting prices directly and in a more targeted manner with less tangential effects. It reads to me as a way to find a rationale to go after a particular policy one doesn't like, rather than being focused on the problem at hand (obesity).
