Extend drug patents into decades? Do tell. You do realize that patents don't last decades in the US and that drugs often have to be patented long before they end up on the market. Plus, as many drugs are made in the US, it seems prudent that we'd want to protect our intellectual property. Do you hold any index funds? Look at some of the top companies in those funds - pharmaceuticals. You'll pay one way or another, either on the back end by allowing other countries to rip our companies off and having reduced earnings on your investments or on the other side when it comes to paying for medicines.
Despite your claims, under the TPP, the pharmaceutical industry didn't get all they want. Take for example a relatively new class of drugs known as biologics (i.e. antibody-based drugs like Humira). They are protected in the US for 12 years. Yet that protection is somewhat limited. It only protects the company's data so that biosimilar companies (aka, competitors) would have to generate their own data for regulatory approval before the 12 year mark. After the 12 year mark, biosimilars can win more rapid approval by conducting limited clinical trials and showing that their product is more or less the same as the brand name drug (same biophysical characteristics, same efficacy, etc...). The TPP will lower this 12 year barrier to 5-8 years (I forget what the exact number was). Regardless, biosimilars will not be the boon to the consumer like generics were in the small molecule space, since biologics have a high cost of manufacture and substantial quality control costs thanks to the way they are produced (so you'd be looking at maybe a ~30% discount compared to the brand name product).
As for drug companies having a stranglehold on America and the FDA at the expense of people, I'm just not seeing it. Just look at the recent muscular dystrophy drug that was approved -
patients lobbied for it and the FDA approved it over the objections of its scientific review board. (On a side note, I think this sets a dangerous precedent: an erosion of science-based regulatory approval.)
Anyway, if you don't like drug patents and what not, what's your solution? Drug companies (encompassing the small startups to the large multinationals) spend billions of dollars annually on research and development. How do you propose they recoup their investments? How should drugs be developed instead of as it is under the current system?
