Answer:
There have been several instances throughout history where farmers have organized a cooperative and organized boycotts against suppliers who charged too much.
One notable example is the Grange movement in the United States, which was established in 1867 as a national organization for farmers. The Grange encouraged farmers to form cooperatives for purchasing supplies and selling their products, and also organized boycotts of businesses that were seen to be taking advantage of farmers.
Another example is the Indian Farmers' Movement, which began in the 1980s and gained traction in the 1990s. This movement saw farmers across India organizing cooperatives and protests against government policies that they felt were unfair or detrimental to their livelihoods.
There are countless other examples of farmers organizing cooperatives and boycotts throughout history, and it remains a common strategy for farmers looking to protect their interests and fight back against powerful suppliers or middlemen.
