It seems like the best solution would be to change the laws to force drug companies sell drugs to pharmacies on consignment, so any unsold drugs get returned before or at their expiration date for the drug companies to dispose or re-certify, as their business model dictates. This is letting the business and free market determine the best way to handle the drugs. Some are so cheap to manufacture it is not worth saving the expired ones. Others are worth recovering.
The only flaw I see in this is the drug companies losing 768 billion in sales, but I think most Americans will sleep ok with that on their conscience.
Farmers talk amongst themselves, a lot, so a crop threatening failure to provide needed service, can quickly become a huge negative in the minds of any farmers shopping for new equipment.
Nothing like "pissing off your best customers to make more profits" as a business model, is it.
