CAIN: "[...] Don’t blame Wall Street, don’t blame the big banks, if you don’t have a job and you’re not rich, blame yourself! [...] It is not someone’s fault if they succeeded, it is someone’s fault if they failed."
ME: OK, well, that's not 100% true. You see, poor people are disadvantaged from the get-go. They do not have a large amount of resources to use in investing for their future. Their money is predominately used for immediate needs - food, energy, heat. The little money that is left over may be divided into investment, education, savings, and consumerism-encouraged bling. It can now be seen that, for the poor (and middle class), only such a small fraction of money can be allocated into investment and education. On the other hand, the wealthy can invest much more into their own advancement.
