I think I haven't explained myself well. I was not referring to exhibition of wealth, but to the effort required to earn a living. Mesuring personal worth in terms of wealth would be a by-product of this, as a signal that you are being righteous and disciplined.

I.e. I was talking about the Lutheran work ethic, which considers hard work and frugality virtuous, and leisure and munificence as moral failures. Other cultures think of free time, and expending on oneself and loved ones, as esencial to enjoy life.
