Maybe we should end the government mandate to burn corn in car engines. Biden seems more pro-ethanol than Trump, I have no idea why.
Corn and ag subsidies have as much or more to do with govt "buying" surplus and "selling" it to foreign countries as part of aid packages. And dominating the world grain market, which gives the US even more indirect control over foreign grain growing capabilities, making others reliant on the US. (Bc investing in local production is risky when the US can just flood the market.)
Separately, most corn grown for ethanol or animal feed isn't going to directly be rerouted to food supply, unless we approach a full collapse type situation (and even then, it would be more market and regulation collapse and black market emergence than due to policy changes).
But keeping those farmers in business and capable of growing table corn next season (with minimal capital investment or changes to practices required) accomplishes roughly the same thing.
In my worldview, a political issue that Biden and the EU agree on, and Trump is less enthusiastic about is probably a good thing.
I don't know all the ins and outs, and would generally prefer moving to EVs, but you didn't actually mention why you're not a fan of this policy?
(Might have been a different ethanol. There are many things that can be turned into ethanol, and it matters if some are worth it and others are not).
