I'd say the government already has a list of where and who all farmers are. All they need to do is consult their own subsidy payment records.
What ever happened to liberty?
With complete liberty corn would be trading at .95$ a bushel and beans would be at $2.00. Non-recourse loans, low interest loans, tax credits, fuel tax elimination... Lots of liberty in those programs.
Don't get me wrong, both my grandfathers and my father own farm land in Kansas, Missouri, and Illinois. I support farmers, and some government programs like the CRP and WRP programs have been wonderful for hunters and wildlife. But if you're complaining about the goverment asking you to register for an emergency I can only assume you're not interested in all these "big brother" handouts.
