Here is a good article on farm subsidies.
It’s going to be interesting to see where Trump lands on the farm bills. If they resemble previous farm bills(I’m pretty sure they will), there is no possible way that a real businessman could claim that the bills are fair and good for “the American people”.
If you’re to busy to read the article, the short of it is that the government taxes you, then gives enormous amounts of those taxes to farmers in numerous ways. The farmer grows the government’s preferred crops of corn, wheat, and soy. They do it with heavy doses of pesticides and herbicides. So much so that they harm their land in the process. Then, they sell these crops back to you in forms that you may not even recognize(high fructose corn syrup, fuel, soy fillers, etc.).
Due to the products that use these crops being subsidized, superior non-subsidized products that do not use them are sold for what seems to be very high prices. The market is fixed and the customer is sold very poor quality and dangerous products that they unwittingly funded.
