After many months of fruitless searching, the Internetz have finally revealed the information for which I seek. If I asked any one of you if you're rich, you would probably say no. By the end of this post, you might change your answer or at least qualify it.
First of all, let's look at the distribution of salaries in the United States (in 2005.) Find your adjusted gross income on this chart and see how you stack up to the rest of America.
If you make $31K/year, you're making more than half of the United States.
We know intuitively that the United States is one of the wealthiest countries in the world, but how do our individual salaries stack up against the rest of the world? Take these global income numbers from the World Bank (in 1998.)
Low Income: Less that $765
Lower Middle: $766 to $3 035
Upper Middle: $ 3 036 to $9 385
High: Above $9 386
The United Nations uses a poverty line of about $2/day. In 1998, 2.8 billion people lived below that poverty line.
I'm not saying that we shouldn't continue to work hard for raises and promotions, but before you complain too loudly, think about how blessed you really are.
