Assuming that 80% of humanity lives on less than $10 a day, and are, therefore, poor, I can just imagine the number of geniuses born poor that will not ever be able to show their geniality to the world.
Imagine how the world would be a better place with all these people working as scientists, philosophers, mathematicians, etc.
