I’d obvously vet my clients based on their fortune:
A bilionaire with a fortune up to 9 billion, then I’d manage to deal with 10%
But at 10 billions to 99 billions, I could only manage to deal with 1%
Also, I would disperse the money, sharing it with the world, while at the same time gathering cameras, computers, and other things I enjoy, thus ensuring that the wealth is not just collected, but actively used and taxes are paid.
Then as the funds I have been tasked with reducing are gone, I am able to accept a new client for this most noble of task.
