“I once heard Jerry Yang, the cofounder of Yahoo!, quote a senior Chinese government official as saying, "Where people have hope, you have a middle class." I think this is a very useful insight. The existence of large, stable middle classes around the world is crucial to geopolitical stability, but middle class is a state of mind, not a state of income. That's why a majority of Americans always describe themselves as "middle class," even though by income statistics some of them wouldn't be considered as such. "Middle class" is another way of describing people who believe that they have a pathway out of poverty or lower-income status toward a higher standard of living and a better future for their kids.”
