If you follow the money, most uber-rich keep a significant portion of their wealth in stocks and bonds. Sure some land and other assets, but their liquid money in bonds.

So the very rich have the most to loose should the bond bubble come undone. Lots of other collateral damage, like pension funds and government deficit spending, but the oligarchs have the most to loose by seeing the status quo change. That is why they need to keep control of the system and keep the debt bubble inflated.
