the primary reason for our higher costs (in addition to lawsuits) is that the pharma companies make the bulk of their profits in the US, as other countries have price controls. in effect, the US subsidizes most of the Research and Development costs of drug companies, and the rest of the world gets a free ride. it's an enormous risk and extremely expensive to bring a new drug to market. throw in the litigation risk, and there has to be a commensurate reward for the risk taken, or the investors and pharma companies won't do it. why would they. Hundreds of drugs fail for each success, and the FDA trial and approval process is long and expensive. for example, i just read about a new cancer therapy that will target cancer cells (chemo kills both healthy and sick cells). however, it will cost a drug company $500 million - $750 million to go through the trials and FDA process to get approval. it will take 10 years as well.
if we we were to implement price controls (like australia does), money for RD into drugs would drop, and the world would be worse off. the worst thing is we wouldn't even see what breakthrough drugs that are not coming to market. if you cut their profits by instituting price controls, taking away their patents sooner and making more generics, are they going to on the enormous risk if the reward isn't there?
no easy solutions really. although govt controlled healthcare in the form of a medicare/medicaid system is the absolute last thing we want. that program wastes 10s if not 100s of billions a year. they simply overpay medicare bills by $20 billion min. imagine if that were expanded nationwide? i'm actually trying to get business for a company to recover overpayments and find fraud.
also, most of those countries are much smaller, and more manageable. australia is offering private insurance these days due to complaints with gov healthcare. so, it's not really fair to compare them to us. although we should look at some of the policies that the successful countries have, and see which are scalable. price controls aren't the answer though. it would be only fair to implement policies that force the rest of the world to share the burden of the costs to drug companies.
