Here's your Forbes Daily Briefing for Thursday, October 10th.

These 11 billionaires have never missed the Forbes 400 list.

Over the 43 years that Forbes has published the Forbes 400,

a total of 1,739 moguls, heirs, and celebrities

have made the ranking of America's richest people.

Economic booms, busts, good old-fashioned competition,

and, of course, father time, have ensured that the list has never featured the exact same 400 people two years in a row.

A few flashes in the pan only make the grade for a year.

Many others spend a decade or two in the ranks before dropping off or passing away.

But a lucky few, the legendary 11, have had staying power,

managing to earn a spot on the Forbes 400 every year since its 1982 inception.

In all, they are worth an estimated $342.3 billion today,

up from $3.8 billion all the way back in 1982 when they first appeared on Forbes'

ranking. That $3.8 billion in 1982 is equivalent to 12.2 billion in today's dollars.

This means they have grown their wealth by some 8,900 percent,

more than double the 4,200 percent growth of the S&P 500.

The average age of the 11 is 88 years old.

When Forbes first published the Forbes 400,

Warren Buffett was the 52-year-old chairman of a 1.5 billion dollar in assets Berkshire Hathaway.

Back then, Forbes wrote, quote, lives modestly, estimated net worth $250 million.

Four decades later, Berkshire is $250 million.00.
