The graph shows just under 23% in 1989, going up past 27% by 1996, then dipping a few years later only to go up to 29% a bit before 2008, then another dip and rise to almost 32% today.
Am I misreading the graph? If not, the percentage of wealth owned by the 1% is on track to have increased 50% over ~40 years. (23% --> 34.5%)
The annual US federal budget is around $7 trillion. The remaining Gates fortune is around $100B. So the feds are chewing through about 70 Gates fortunes per year. And that doesn't even account for state and local spending.
The idea that the system is crumbling because all the money is ending up in the pockets of billionaires does not pass the sniff test.
