Another possibility is that modern wage laborers are forced to wear a mask of positivity and say "yes, absolutely!" or "awesome!" to everything, because they are terrified of losing their jobs and not being able to keep their necks above water, in a world where fewer and fewer people own most of everything.

Perhaps you yourself are wearing this mask of positivity, when you come here and say that this makes you "pretty happy about the world".

The road to hell is paved with good intentions (and blindly following simplistic metrics).

It's healthy to say no sometimes.
