Where is that wealth now, I wonder if it's really all that secure. History has shown that ill-gotten wealth can be made transitory, if someone tries hard enough. Seen any Medici lately?
The main branch, the ones with the money and power, did die off, and their lands were given to Maria-Theresa's husband as compensation for him losing his ancestral lands ( Lorraine, because the French king didn't want Austria to have land even closer to him) after the war of the Austrian Succession.
