It's not a counterpoint. For a rich person, each additional dollar is worth less than it is for a poor person.
Rich people are a counterpoint because there are people with incomes the size of a small country, and they are still striving for money. Given the diminishing utility of familiar pleasures, I think its likely that constantly reaching for "more" is the norm, rather than the exception.
I continue to work because I genuinely enjoy what I do.
