Written before tariffs were in place? Are you trolling? Trump's tariffs began in January 2018, while this article was written over a month and a half later. A calendar might help you.
Further, the article, which shows that Farm BK's had already been growing before the tariffs had any real impact, so to blame BK's solely on tariffs is, again, an over simplification of a complicated issue. As evidenced, you pointed to one product (soybeans), and one type of farmer (soy bean farmer). You are not taking a wide lens view of the farming industry.
