Gallup has a fascinating poll asking Americans what level income they need to earn to consider themselves "rich". The results are fairly surprising:
The median answer is fairly surpring: $150,000. That is, a majority of Americans think that anyone making more than $150,000 a year is rich.
To offer some context, this income level will put a household almost exactly in the top 10%; and individual making this amount of money would fall in the top 2%. All in all, It is a surprisingly accurate guess. The top bracket for Federal income taxes, incidentally, begins at $379,000.
