It was really tough to find - I used Google. My guess is that you will click on the "Unclaimed Money" section first because you have yet to put your money where your mouth is.
To President Obama - try to remember that someone making $250,000 and has six children is not comparable to Warren FREAKING Buffett.
Finally, if you are so worried about "fairness", then let's discuss a flat tax. Then guess what - everyone pays the SAME RATE (as fair as you can get.) Amazing, I know.
