To say that there have been no cures in over 50 years is simply not correct. Many childhood leukemias and about 80% of lymphomas are now curable with mixed chemotherapies and even bone marrow transplants developed since the 1970s. Prior to that they were 100% fatal. A wide range of antibiotics have come on line in recent decades to address mutations in bacteria, which would have proved fatal to millions. The anti-virals are also fairy new and can clear up or reduce things like shingles and herpes. Smallpox was entirely eradicated within the last 50 years, worldwide. It was just over 50 years ago that polio vaccine was introduced, and polio used to kill or cripple tens of thousands of kids in the US alone every year. As for autoimmune diseases, which all seem to have at least some genetic factor, that's not going to be "curable" until we learn to test for genetic tendendies and manipulate genes either in utero or at birth. I really don't have any problem with a drug company making a buck off my current prescription for 6mp and using that money to fund research in genetic engineering, which a lot of them are doing.
I suppose we could just tell the pharma companies to go pound sand and go back to the era, which includes parts of the 20th century, when all doctors had to offer for even a simple pneumonia was a cold compress and the number of the local funeral home.
Honestly, I really can't buy the suggestion that the entire medical establishment wants people to be sick. They make money from cures, a product people are -- not -- dying to buy. Good for them.
