But that is not the situation. In reality, the situation is: A rising tide raises all boats.
The global pie is getting bigger because GDP is growing faster than the population:
- GDP Growth since 1999 ~2.5% annually [0]
- Population growth since 1999 ~1.3% annually [1]
- % of world population living in extreme poverty has more than halved since 1999, 29% to 10%. [2]
Meanwhile, the wealth of the top 10 wealthiest in the world has grown at a rate of ~4.5% since 2000 (not adjusted for inflation) [3]
So perhaps a more accurate depiction would be: A rising tide raises all boats. But it raises some faster than others.
