Next Year We’re All Gonna Make The List — Thirty years ago, when Forbes published its first Forbes 400, a net worth of $75 million would get you on the list. Today it takes $1.1 billion. In the last year alone, the cumulative net worth of the wealthiest 400 people, by Forbes’s calculation, rose by $200 billion. That compares with a 4 percent drop in median household income last year, according to the Census Bureau. One would be hard pressed to find a clearer example of how powerfully income inequality has taken root.
