As we can learn from your Science and Technology Section, the Bible is right when it says that the poor will always be with us (“I Am Just a Poor Boy Though My Story’s Seldom Told,” April 4, 2009). According to several researchers you cite, it all comes from stress and nothing but stress. The reason the poor are stressed is that they are at the bottom of the heap both socially and financially. The stress damages the working memories of children raised in poverty, and this leads to difficulties with learning. And difficulties with learning lead to poverty, which thus passes from generation to generation ever since the Bible was put together. Neat, this. Therefore, the heap will always be with us, as will the rich at its tip, whose wealth will also pass from generation to generation forever. I am sure the intrepid researchers will soon demonstrate the obverse of their proposition, as outlined here, which will undoubtedly come with an appropriate biblical reference, too.
