I like this a lot. It's a great idea, and very well done!

The one thing I do want to point out just to be helpful (not to be critical or in any way thread fart) is that your average wage stat for the U.S. is incorrect. I think there is the possibility that you might get some potential U.S. customers who would read the $26,000 stat you've provided, and click off feeling that it isn't accurate or true. You definitely don't want to risk that so early in the presentation of your material, so I'd recommend updating the figure.

Anyway, the avg. annual wage in the U.S. per the US Department of Labor/BLS was $36,764 as of 2002.
