The whole problem stems from the patent system.
We allow big pharma a complete monopoly on developed drugs for 50 years. Which was bad enough before, but with Disney screwing up that 50 year mark, right now patents don't have expirations for them. In places other than America which don't have patent laws, when one company innovates, everyone else re-engineers and copies. The problem is the company that did the innovation spent money developing the product in far excess usually than the other companies that just copied their work. So they have a need to recuperate their initial investment. That was why we have the patent system. Which is good in principle, but very BAD in execution.
I believe new laws and changes to the patent system are required at this point, as the current system is just fubar. Here is what I think should have been done, and my sentiments in this aren't my own.
First, any company submitted for a new patent in the health and medical field must show initial development costs and regular overhead costs for the development of the product. That that sum of developments, whatever it is and has to be audited at the companies' initial expense for which can be recuperated, and then use that as a baseline for how long a patent will last when factoring sales costs and profit margin. Also a cap on profit margin would have to be set for this to work for these product types only.
Here is a simplistic example. It takes a company 10 million dollars to develop a new medical product. That cost includes R&D, expenditures, overhead of maintaining facilities, and labor costs. That company ventures that operating costs to bring the product to market, logistics, and other overhead is going to be a 2 million dollar a year cost. The profit margin cap is set to 8% (which is generous IMHO). So whatever price the company sets their product at will factor in to how long the exclusivity of the patent lasts. Reports have to be made back yearly of revenues and losses for the product as well no different than a shareholders yearly report to the patent office. This way if adjustments are required they can be made.
I still say a hard limit of 50 years as the upper limit for a patent is fine, but if a company wants to charge 100,000 a pill and sells a million pills per year. The patent protection won't last them very long. It basically is meant to give a company some market protection and slight initial market edge once the patent goes away.
Currently, the system is setup for propping up monopolies that are allowed to freely fleece America because there is no fair and free market principles being applied. Which is fine when all companies are being fair and ethical themselves, but when the companies are existing now for pure greed the current system is shown to be horrible.
