There is nothing wrong with personal responsibility, the issue starts and ends with the patent system.
Patents are government granted monopolies, reducing the length or eliminating the exclusivity of patents would solve the high price to consumer problem completely.
The problem is actually created by the government in the first place. If you fix the length of the patents or eliminate the patents in the first place the cost of drugs will drop close to the cost to produce them.
Monopolies are well studied in economics and the effects of monopoly pricing due to government granted patents are what we see here, this is a government created problem not a free market one.
The issue is entirely government granted patents, if multiple companies could produce the same drug the price would fall to the cost of materials and labor plus some marginal amount. If I am the only one who can produce the drug I have a monopoly and can set the price extremely high and that is what we are witnessing.
You don't need price regulation if you reduce the length of the patents or get rid of the patents completely. Keep in mind patents are a government granted monopoly, the problem is the patents not the prices. If someone else can make the drug for 800 and is happy to sell it for 1000 then it won't be sold for 84,000 anymore because no one will buy it for that price.
