Punch in your income at the Global Rich List and see where you rank:http://www.globalrichlist.com/index.phphttp://www.globalrichlist.com/index.php
I'm in the top 0.83% of the world's population. Puts things in perspective, when you consider the stats on the site:
$30 could buy you an ER DVD Boxset OR a First Aid kit for a village in Haiti.
$73 could buy you a new mobile phone OR a new mobile health clinic to care for AIDS orphans in Uganda.
