The story in that graph is about change in productivity WRT change in wage, though. In order to "fix that" you either need to see an increase in wage growth or a decrease in productivity growth. It seems that your argument is that it (UBI) will increase wages with no (or minimal?) change in productivity. Are you counting the transfer payments in your increased wages, or are you implying that wages will start growing again in addition to the payments?
