You should define what you mean by rich.
Colloquially, when speaking of 'eat the rich' its typically a reference to people with net worths exceeding 25 million or more with substantial cash generating assets there in[0].
Rather than some SWE's making 250-500K a year and perhaps retire with 5-10 million in assets with smart investments over the course of 20-30 years. This gets edged down into 'upper middle class'. Sometimes the term. 'Well off' is used (somewhat nebulously) to refer to people in that bracket.
Of course there are exceptions, but these seem to be the common trends in these discussions.
Therefore, I ask again, what exactly do you mean by rich? Because the most colloquial definition is unlikely to be common anywhere, even on HN
[0]: Whether folks realize it or not, this is approximately where the real difference between 'well off' and truly wealthy start to set in. It differs a bit by state (in the US) and country, but its a decent enough approximation for this conversation.
