Why is there a gap between productivity vs wage, that began in the 70s?

Question

I think everyone’s seen the famous graph from the Economic Policy Institute, that show that while Productivity has been growing in a steady and linear fashion decades after decades, wage began to stagnate in the 70s.

Since the 70s, wage have grown about +0.6% per year, while productivity has grown at an average of 1.4% per year. That gap is enormous and it is compounding over time.

Can someone me why it’s happened?
