I respect your enthusiasm for Trump and his policies, but cheap pork or fewer markets will mean farmers will simply reduce growing pigs.
Argentina’s socialist government tried this in 2014 on their big beef export industry. The President Kirchner was a fan of Hugo Chavez. She thought - why not ban beef exports, and we’ll have plenty of cheap beef for poor Argentinians?
It worked for 3 months, when farmers slaughtered their cattle and packing plants shut-down. After that, domestic prices jumped higher than ever.
Prices for food in the US should be higher. It is insanely subsidized today between direct subsidies and food stamps.
When did that happen?
It’s basic economics. Simple supply and demand. If you can’t make money producing something then you will stop producing it until the drop in supply causes the price to rise to the point you can make a profit again.
