People are turning Zombie Everyday

People are becoming Zombie Everyday
Could just be me getting older, but I notice a surprising amount of people are generally 'out of it' or have low-grade mental illness in everyday life. I even know a lot of people who are successful in the traditional sense, but are clearly mentally imbalanced, self-destructive, and just generally messed up. What's going on?

Science seems to support my observations; turns out there has been a massive increase in depression, anxiety, and mental illness in the World over the past couple decades. Yes, there is less stigma around these issues now so more people are probably willing to seek out treatment. But still, the numbers are off the charts: Social Conditions and Depression Statistics.

People shouldn't be THIS stressed/confused/sickly. It doesn't make any sense. I'm not sure if it's the food supply, fluoride in the water, excessive TV watching, or what but I see people hardcore stuck in the Matrix every day. What do you guys think is going on?
