Show me the data that supports this claim. Big claim, zero citations. As an American I've never met anyone who thinks wealth reflects "wealth of the soul."
In my experience people here are Christian, in which case there's that verse about heaven and wealth and the eye of the needle (Google it) or they're atheist and don't believe in souls.
