"Hello, is this the Murdoch family office? I'd like to speak to your team's permanent director of assets strategy about how wonderful it would be for your income to drop by ten to fifteen percent."

You could do the same with the accounting team on retainer for the US Commerce Secretary's family portfolio, or the US Education Secretary's family portfolio, or the US Interior Secretary's family portfolio, or the head of NASA's family portfolio, or the Middle East Special Envoy's family portfolio, or the Administrator-in-Chief of the Small Business Administration's family portfolio.

These are all individuals with a net worth of over a billion dollars who each separately employ a full time accounting and financial team with its own IT and HR just to maximise family income. What's ten million a year in operating costs versus at least sextuple that in return?

Each oligarch of size is the figurehead of a corporation dedicated to number go up.
