Many of those types of crops used for feed aren’t really aligned all that well. Corn for instance isn’t going used so heavily in a plant-based diet as it is subsidized (corn is the most subsidized crop in the US). There is also separate food-grade and feed-grade soybeans. 90% of US soy production is going to feed (and not to mention a good portion of the other 10% is going to soybean oil which is not super helpful for a plant-based meat)
90% of U.S. soybeans produced are used as a high-quality protein source for animal feed
Further, they are still getting massive amounts of direct subsidies
The Department of Agriculture has spent almost $50 billion in subsidies for livestock operators since 1995, according to an EWG analysis.
By contrast, since 2018 the USDA has spent less than $30 million to support plant-based and other alternative proteins that may produce fewer greenhouse gases and may require less land than livestock.
