I strongly disagree.
Americans' health is fairly good – not the best among developed Western nations, but far from the worst – significantly better than 3rd world nations. Yes, people are overweight. But our leading causes of death are heart disease and cancer with average life expectancy in the 60s and 70s. These are rich men's diseases. In Africa and Asia, people live decades less, and die of hunger, malaria, bacterial & viral diseases, and most of all of contaminated water supplies. They don't survive long enough to develop heart disease or cancer.
Auto-immune diseases only seem to be an exploding new epidemic. They were always there. Only more recently we have developed new methods of identifying and diagnosing them. Newly developed methods of treatment are already emerging.
RFK's ideas are downright medieval. If all of them are implemented, especially the need for widespread vaccinations, our nations health will be driven back into the dark ages. He would destroy America's leading role in medical & scientific research resulting in the end of our world leading position in research of understanding disease causes, their diagnoses, and the development of new drugs to treat them.
Most of this research is sponsored by the US Dept. of HHS. The NIH and NCI spend a lot more money than big (and small) pharmaceutical companies. America is the world's Mecca for scientific & medical research. Other modern western world countries send their best & brightest to study and learn how the USA does it. Most return home to put these lessons into practice. The CDC is the world's leader in active surveillance of newly emerging infectious diseases, especially viruses. Again, other nations want to send their people there to learn. The US FDA may be slow to change it's very conservative approach to drug safety & effectiveness, but it is the gold standard of the world. A standard that drug regulatory agencies in other countries all emulate.
RFK would torch all of this.
