Great graph. What it says is that the third world has been raised up, but at the expense of the poor in the developed world.
I remember the 50’s and 60’s. The average person looked forward to a brighter future. the disparity between the worker and the CEO was perhaps a factor of 30.
As production moved offshore worker pay went down or stagnated, while CEO pay went up a factor of 10.
Those in the first world benefited from lower prices of imports, but could only maintain their standard of living through borrowing as people lost jobs, or were forced to take lower pay.
A UBI would have enabled people to buy the same goods they did on borrowed money, but without the debt. The same demand would have pulled third world workers up — but not at the expense of poor in the first world.
The UBI would not have stopped people taking the available work at whatever wages were offered as any money they earned would have added to their well-being.
We would have had a reduction in global poverty, continued production at home (at the wages offered), lower debt and a more vibrant society.
It is a system problem.
