It is indeed true that poverty is close to stupidity but we can never say that those in the poverty all exhibits stupidity. There are instances for some countries where some people cannot escape poverty because their government is full of corruption and power tripping. No matter how hard they try to earn lots of money, they stay under the manipulation of those in the higher table. If you have all the capabilities to have a stable and high profited job and you stay in poverty, you could be considered as stupid totally.
