I can’t positively recommend reading this excellent article (a collaboration between Pro Publica and The New Yorker). It’s full of excruciating medical detail. But if you’re hardy enough to do so, there’s a lot of food for thought.
A thought: the profit motive in medicine will kill most of us eventually, even destroying those who can afford treatment.
Another: patriarchy imposes a huge burden of sorrow and suffering on men. That’s not the most important reason to be against it, but it’s a reason.
