Every exported agricultural product has a lot of OTHER industries with a vested interest in agricultural exports. You have the barge and railroad industries that move grains to ports, along with elevator operators and longshoremen at the ports. You have all the industries that supply these, too. You also have the trucking company whose president I met with earlier this week ... whose contract to haul grain to an East Coast port may be in jeopardy if the global marketplace for his customers' products changes as a result of foreign tariffs.Every action you describe above would be the same for both domestic and imported agricultural products. As a matter of fact, a tariff imposed by China on our exported agri products would INCREASE all of that secondary activity, not decrease it.
I'm not sure I understand what you're trying to say.
If the U.S. produces X million tons of an agricultural product annually, and currently ships 20% of it overseas to foreign buyers, are you suggesting that there will still be the same level of activity among supporting industries if that 20% disappears or is scaled back dramatically?
