The pandemic has gotten me thinking about an old hypothetical; namely, what the ramifications would be if some individual happened to be a trillionaire (in today’s dollars, that is, not future-inflated dollars.) Basically, someone like Bill Gates or Jeff Bezos, but orders of magnitude wealthier.
Discussion of things like private jets, yachts, mansions would be pretty meaningless; such an individual could buy just about any luxury known to man. What would be more pressing, I think, is that such an individual would essentially wield quasi-governmental power. His or her wealth would be so immense that it would have national or international implications, and hence, would figure into governmental policy. Governmental decisions would have to take this Individual X into account.
In addition, in times such as a national epidemic (like the coronavirus in America right now,) such an individual would be heavily pressured to donate or spend money to stimulate the economy. People would regard him/her more as an unofficial arm of government than a private individual. The government would probably try to cut taxes and cajole this individual into donating money instead.
Such an individual could also wield considerable influence in elections (i.e., “I promise that if such-and-such a candidate is elected President, I will then spend $500 billion on helping rebuild highways, schools, infrastructure,” etc., but not if the opposing candidate wins,) although that might be considered illegal election tampering.
Finally, since such an individual would have to essentially command the equivalent of Amazon + Microsoft + Apple + Boeing + Facebook + ExxonMobil + Google all at the same time in order to get such wealth, there would be intense pressure to pass laws to split up his wealth and prevent any one such individual from having so much power in his hands. Maybe more antitrust laws.
