stupidity is so close to poverty, do you agree with such a phrase?
if it yes, means the poor are the fools.
I want to know your opinion.

No I don't agree with your statement. A lot of poor people are really intelligent but they don't have the resources to succeed. Being abused as a child, growing up in a poor country filled with violence you will have a very small chance to overcome that.
Most rich people I know in real life are either stupid with good connections or just got extremely lucky.
Success has nothing to do with poverty or richness. One who struggles get its reward. Poor people are blessed with the same mind and same level of intelligence. For me, I think poor are more successful as they are more hard working due to the difficult phase of their lives. The hardships they faced, make them more experienced and knowledgeable. They know how to best use the available amount of resources and bring benefits out of it.
