Non-religious nations have higher quality of life
Definitely holds true for my second home, Japan. Safe, well-organized,
peaceful, the Japanese are super-technologically savvy (far ahead of the
US), have socialized medicine, and are generally, less, well,
dysfunctional. That being said, I love American sense of humor far, far
better (we can make fun of ourselves--whoo-hoo!) Also love our green
spaces and free (rather than paid) parks and libraries. But yes, that
non-religious nations have a better quality of life I find unsurprising.
Not being religious frees up the mind from the idea that we are somehow
not responsible for the bad stuff we do because of a higher calling. My
mantra: today's religions are tomorrow's mythology. Fun to study, but
wouldn't want to be subjected to it for real.
