When Forbes began tracking the wealth of the richest 400 Americans in 1982, it only took $75 million to make the low end of the list. Today, $1 billion is the minimum requirement. If you added up the net worth of the 51 richest Americans last year, the trillionaire mark would be reached. This year, that number is down to 37 individuals.
It is a matter of when, not if, according to many wealth experts. Steve Kraus, the chief insights officer of Ipsos MediaCT, which releases an annual survey on wealth, said he would not be surprised to see a trillionaire within the next 25 years.
