The use of HFCS by the beverage makers is purely due to the inflated price of sugar here in the US. The Maffia-Like cane sugar grower lobby has the US government supporting high import duty on cane sugar. Plus, it benefits our corn growers.
Hershey (who doesn't have the option of using anything other than cane sugar) has been thinking about moving their manufacturing operations to Canada due to this problem.
If you shop at any of the small Mexican markets here in so-cal, you can find imported Mexican Coke. The Coke bottlers here are starting to get P.O.'ed about this because it's beginning to eat (abeit slightly) into their sales.
Real sugar soft drinks taste so much better than their HFCS counterparts.
