Amazon's Jeff Bezos, Facebook's Mark Zuckerberg, Bill Gates, and Steve Jobs did not start out wealthy, and actually added to income inequality, but we all benefit from their creative effort.

If you live in a ghetto and really want not to just change your life and your family's life but change your ghetto's life, make your ghetto a good neighbourhood, learn science; try to be like Mark Zuckerberg, Bill Gates and Steve Jobs.
