Crap or not that is reality of how discounts are applied.

Chicago is not a "real" market for grain.  The cash market is the real market, that is where end users buy the grain that they need.  

By widening the basis they are telling you that they have enough grain and are not willing to pay what a suit in Chicago says corn is worth.

There is plenty of corn out there.

If you don't like what you get for your grain you could always use it yourself somehow and show all of the other end users how to get rich using that "cheap" grain.
