ELI5: Technology and automation has led to much greater efficiencies and output for every human in the workforce over the last 50 years. How come this hasn't led globally to less working hours or a shorter work week for the average worker?

EDIT: Replace 'every human in the workforce' with 'most people'. I agree efficiency has not been gained equally across all professions.

I’m not sure if there’s a way to answer this question without politicizing it to some extent. 

Basically, business leaders didn’t see the gains in efficiency as an opportunity to reduce hours for their workers. They saw it as an opportunity to make more stuff for less money and thus make more profit.
