on the contrary, i think people are born with different IQ levels- it's a combination of nature/ genes and nurture. and sadly i think the poor do have lower IQs/ brains. am not talking narrowly here about what they would score on a standardized test, but on a broader definition of "brains".
apart from genes, the lower IQ might be attributable to their circumstances- poor health and nutrition, limited opportunities for advancement, to gain exposure, limited education and confidence levels etc. These all play a symbiotic role in how the brain/ mind and in fact the entire personality develops, and in whether someone would have the zeal or the talent to rise above their station in life.
as for typecasting, that's what the debate is about. not that we are necessarily doing it for any noble reasons, but typecasting is implicitly what researchers do to develop solutions.
