Almost off-topic, but I see three layers: Poor: Unable to make enough money working to sustain your lifestyle Middle-class: Must work to sustain your lifestyle Rich: Work not required to sustain your lifestyle That implies that there are two ways to becoming rich, either you can make boatloads of money, or live below your means and create a savings that sustains you.
