how could that NOT be “mistaken” for a racist comment?
The expression was used in my youth to describe anyone who had come into a sum of money and lavishly and foolishly spent it on things which were of little value to their protracted survival, regardless of other factors.
It was superseded by the less controversial expression "nouveaux riche", but that, semantically, more aptly described a class of newly monied social climbers who confused the (often questionable and overstated) trappings of wealth with class.
