The United States has subsidized sugar for 82 years. Like most federal subsidies our programs subsidize producers rather than consumers—the specific objective of the programs have been to raise sugar prices and it’s been effective. Americans pay $300 million per year to support the program. For more information on U. S. sugar subsidies see here.
Our sugar subsidies have had a number of consequences. For example, they have encouraged the development of the Everglades for sugar production with serious environmental consequences. They have made artificial sweeteners and corn syrup more competitive with sugar than would otherwise have been the case and there is some evidence that artificial sweeteners and high fructose corn syrup actually cause cravings for sweets. Ironically, recent studies have found that artificial sweeteners, specifically aspartame, may be counter-productive in weight loss.
