Poor in perpetuity?

New studies claim that the stress that the poor inevitably suffer adversely impacts children’s working memory, causing them to be under-achievers in later life and thus remain poor.
The researchers found that those who had spent their whole lives in poverty could hold an average of 8.5 items in their memory at any time. Those brought up in a middle class family could manage 9.4, and those whose economic and social experiences had been mixed were in the middle.
