I don't think our society has any focus on happiness, it's not easily measured or produced and there's little proof that it'd benefit the economy..
I mean..
What if people suddenly discovered that enough food and shelter is available, that they could do maybe a days work a month and just walk around to smell the flowers the rest of the time?
There are many people for whom that is true (chiefly the retired). The ones who are physically able generally choose to do something marginally “productive” than continuously smelling flowers. (Perhaps that’s related to what got them to a position to retire, whether a work ethic, other personal mindset, or programming.)
