You obviously did not read or look at the references I provided, so do you think providing more will help? The argument goes like this poverty affects cognitive development in multiple ways. It increases stressors, it affects grey matter formation and ability to self regulate emotion, it affects self confidence due to being treated poorly which affects performance, it increases likelihood of a range of social ills that also act as a block to performance such as drug/alcohol abuse, teen pregnancy etc. The money itself is a factor because real wages have been stagnant for 35 years while tuition has gone up markedly in comparison. The poor run through a cycle of striving to overcome their problems due to lack of resources and then being blamed for them. Conversely the rich do not suffer these negative circumstances, in addition they are praised for performing well though largely that is a condition of their birth and they actively game the system to their advantage. There are increased signs of narcissism/sociopathy correlated with income. In addition, they are tied to social networks that actively exclude the poor as is seen in both the financial sector and in the ivy league. In addition racial issues are a factor with less qualified whites more likely to receive management and ivy league acceptance over their peers due to subconscious racism. I can provide referencesfor everyrhing I have said, meanwhile you are just saying "I don't believe you." Without providing a counter argument.
