Richest American

The rich haven't gotten richer--or poorer--this year. The price of admission to this, the 27th edition of The Forbes 400, is $1.3 billion for the second year in a row. The assembled net worth of America's wealthiest rose by $30 billion--only 2%--to $1.57 trillion.

Rising prices of oil and art paved the way for 31 new members and eight returnees, while volatile stock and housing markets forced 33 plutocrats from our rankings.

With a net worth of $57 billion, Bill Gates remains the richest man in America despite losing his crown to Warren Buffett for a few months this spring. Buffett's shares in Berkshire Hathaway have fallen 15% since February.

Newcomers to the list include fertilizer tycoon Alexander Rovt, car dealer and art collector Norman Braman and Patrón tequila founder John Paul DeJoria.
