Adding to my last comment: I went to the USDA ERS table of the following:
Wheat Data: Yearbook Tables
Wheat: Supply and disappearance
And for the last 3 years and for many years before that, there was always a surplus supply in millions of bushels every year, even after exporting whatever we exported. So much for no surplus in this country.
I just checked the surplus for Durum, rye, barley & oats. They all had surpluses every year carried over to the next year, even after all the imports and exports.
