Well said. We all should really focus on our own potential and see the potential in others.
I do believe that it is possible to rise above your station.
And while you spoke primarily about wealth, people also see it as the opportunities they have, or the ability to move from class to class or fulfill their desires. Wealth can pretty much provide that, which I think is your main point, but I believe the opportunities to improve are everywhere, as you also say.
If we can care less about what others have, while working diligently toward what we want, potential gets realized.
I, too, have found that building a life, one that includes family, friends and memories, provides wealth, too. A legacy rich with joy and happiness.
