Also the children of the affluent have more time since they often don't have to work. In fact I was explicitly told by my parents to study rather than work. Their reasoning was that the whole point of them grinding their butts off working was so I could have the best education money could buy (they grew up poor in post WW2 Japan and were dirt poor immigrants in grad school in the 70's). Worked out for me, but there's no denying that I had an enormous edge over the vast majority of my peers.
