I'll try to find you more sources, but this should suffice.

The wealthiest 1% (96% of that wealth is tied up in things other than their house) control 39.5 of the country's wealth. Oh, and that only accounts for the declared assets of the 1%. Surely, if they're "smart" enough to accumulate so much wealth, they have found ways to hide some of it.

The top 4% control 64%.

It's amazing that most Americans are unaware of the actual wealth distribution in this country.

Narwhal,
Don't worry, I was just kidding. Hate those Princeton kids.
