"Basically, the mega rich are mega richer," said Forbes Senior Editor Kerry Dolan regarding the magazine's annual list of 400 richest Americans.

And that goes for the richest man in Florida, Carnival's Micky Arison who appears at the 70th spot on the list.

His net worth soared by nearly one billion dollars since last year even with the Costa Concordia wreck that killed 32 people and a fire on Carnival Triumph that stranded passengers.

Who are these billionaires? Most are men, many are involved with oil or pharmaceuticals, and several own sports teams.

Of the 400 billionaires, 273 are self-made, according to Forbes, 71 inherited their wealth, and 56 inherited a portion of their worth but are actively growing it.
