A thought just struck me, but I wonder if the difference between the Billionaires of Today and the Monopolists of Yesteryear is that the wealth and power of the Billionaires are tied up in publicly exposed assets (stocks, etc) as well as networked wealth. Make the wrong political move, and people tank your stock into oblivion.
But what are you going to do to Carnegie? Not have steel? Rockerfeller says something antithetical to Elite Beliefs? Good luck getting oil.
This is relatively well known. Monopolists had very real wealth with a high floor value and controlled large portions of the supply chains needed to build big things that lasted.
The Silicon Valley 'elite' of today has wealth predicated on theoretical value calculations of things the world isn't even convinced it needs. Monumental difference, and it significantly changes how these guys operate and what legacy they leave.
