In Iran, there is a wide-spread belief that the USA throws extra wheat it produces into the ocean to keep the prices high.
The official website for the Iranian presidential office [Persian] quotes Mohammad Reza Rahimi, former First Vice President, in 2008 or 2009 as claiming that a country threw its wheat into the ocean to increase the international price. He doesn't name the country here, but because everyone has heard this story before, the US is the country that comes to mind.
This article [Persian] is from a less famous person that claims that the US throws wheat into the ocean.
So, my questions are:
Does the US government or any US-based company currently destroy agricultural products to keep prices high?
Did the US government or any US-based company destroy agricultural products to keep prices high at any point in history?
Has the US government or any US-based company destroyed agricultural products in a large scale for any other reason that could have been falsely attributed to keeping the prices high?
