See here the latest level of Household income it takes to be considered a high income earner. You will be surprised at how little it takes to be near the top!

Interesting graphic from the Wall Street Journal.  The article states these figures are "national" and do not completely reflect regional differences in income relative to cost of living.

Numbers at the bottom left indicate what it takes to be in the different percentiles of income.  A key word is "Household"---this could be the income of just one person or multiple people that make up a household.

For instance, you could have two teachers married to each other, both earning $55,000 per year (not unrealistic) and be considered in the TOP 20% of income earners.  Surprised you are that high in the "rankings"??
