Something like a Yearbook of Facts, or AlmanacSure it does seem like a good idea to have a site that somewhere.
Since no one at DU was able to answer my basic question...Dude, I think your question was answered. That 50K was the median,
not the mean income of families. So if Bill Gates makes 1000 times as much, that number won't change at all.
Here's a cute site that shows how insanely sharp the income curve shoots up at the end:
http://www.lcurve.org/By the way ~500G$ is spent on the military so that's a good fraction of GDP. The biggest parts of GDP consumption and investment.
When Stalin wanted to know his economy was getting stronger, he'd compare the amount of say Pig Iron produced this year vs. last (and he'd send people to Siberia if the didn't figure out how to "improve" these numbers").
Our modern economy doesn't let you count commodities to measure production. Products are constantly being improved and replaced by better ones. So what we do is try to use market to estimate the value of goods produced this year with the value produced last year.
Example:
Last year you buy for consumption a PC with a 1GHz processor for 500$.
This year a business buys one with a 2GHz processor for 500$.
According to the way we calculate GDP, both machines are of equal value!
All you economists can look at is the market values of different things at particular times versus the currency and the volume of activity. Which leads you to the next fun problem, defining inflation.
I hope this doesn't confuse you more then helped. I'm no expert, but just pretend your a scientist trying to figure out what the economy is doing. What would you measure?
To get a good idea of what makes up GDP and how it's calculated look here:

Here's a quick wrap up:
Gross domestic product....... 10,985.5
Personal consumption expenditures. 7,753.2 (next 3 are a break down)
** Durable goods................... 941.1
** Nondurable goods................ 2,209.4
** Services........................ 4,602.7
Gross private domestic investment. 1,671.4
Net exports of goods and services. -494.9
Government consumption expenditures
and gross investment............. 2,055.7
So it looks like Americans spend most of GDP on personal stuff, then government services, and then we invest.
