According to the democrats, you're rich if you make over $25K a year. In reality, it has more to do with where you live. $40K is more of a generally accepted marker amongst most Americans. However, if you live in L.A., New York, or other such places with high costs of living, you would be in poverty at $40k per year.

Where I live, the "general" rule applies, and I'm sitting comfortably inside that bracket @ $55K per year.
