People have lost faith in the medical establishment and industry. Long time ago we managed to erradicate smallpox, but nothing since. I try not to be too cynical, but as long as it is hugely profitable to treat rather than cure, then we will always be unhealthy. It's also a little like how Ike after WW2 was against making an industrial military complex and industry as if war is always profitable, then there will always be wars.
There has been much erosion of trust in big pharma and the medical industry and of instituations like the WHO, FDA or the AMA etc. in the recent past as much detrayal is suspected... and let's not even get started on the Chinese vaccines, WHO chief Ted Dross covering up for Beijing, and why the files for big pharma on Covid/vaccine are sealed for 75 years and they have been given immunity from prosecution etc. I'm not a huge conspiracy theorist, but there is plenty that doesn't pass the smell test and is highly suspicious... people just don't blindly trust or believe what they are told now, so it gets even more murky and opaque, and maybe by design.
