There most certainly is not, full stop, and this is the psychological aspect to which I am referring and colorfully exploiting in my anecdote. Someone who hangs out on Hacker News should realize this, since our profession in particular has minted a large number of people who are exorbitantly wealthy and still wear Old Navy flip flops and hoodies. Poor people also inherit Prada, and quite a few hucksters within multiple industries dress in a particular way to exploit this psychological conditioning while having no money at all.
This is the entire point of my comment, and assuming that relationship exists says more about your subscription to certain expectations and conditioning about people than your remarks on "business." It's actually a disservice to yourself to assume there is a relationship between wealth and style based on customs that are increasingly becoming dated.
