IMO, we are already there.
Yeah, we are. When a site like FR has a group of people who believe in this, we're in trouble.
As gridlock said, we've moved from people believing in a default state of life to a default state of death. Our instinct is to fight for life. When we are injured, our bodies naturally struggle to repair the damage, struggle to breathe, we fight. We spend countless dollars on medical research, medical treatments, etc. to find a way to survive just a bit longer. It's just natural that we work to live. Yet in the face of all the daily evidence that we fight to live, society has determined that those unable to speak for themselves would rather choose death.
