As Thomas Sowell says "There are no solutions. There are only tradeoffs."

I'm sure you're right about increased diagnoses (as in, I know for a fact that's true), but I'm very skeptical that it explains the orders of magnitude increases. The other part is that we aren't just talking about marginal cases. The rise of serious cases that would definitely have been recorded as something is very large.

The bottom line is that we are clearly sicker than we used to be, despite having come up with many cures and treatments for the illnesses that used to plague us.
