A majority of what you wrote is objectively false FUD. The only thing that I found accurate is:
> it's getting more expensive and less efficient
There have been a ridiculous number of medical advances in the last few years, advances that are actively improving and saving lives as I write this. Remember that time we had a pandemic, and quickly designed and produced a massive number of vaccines? Saved millions of lives, kept hundreds of millions from being bed ridden for weeks? The medical technology to design those vaccines, and to produce them at that speed and scale didn't exist 20 years ago. Cancer treatments, which you specifically mentioned, are entirely better than they were 10 years ago.
The actual issue, which is the only worthwhile thing you wrote about, is cost and availability.
