Rather than re-allocating their money across every human on earth, why not allocate it inversely proportional to the net worth of the recipient (and maybe also local currency conversion rate), to uplift the poorest folks?

Could probably choose a lower number, too - say, $100M. Nobody needs anywhere remotely close to that.

I’d rather make sure everyone has everything they need for at least basic life. Healthcare, education, infrastructure to name a few. Food for schools. I know a lot of countries already have this. But many don’t even have access to clean water. Ideally worldwide. And throw corrupt politicians and military overlords in there. Although many of them would be counted in the >$1b. Get rid of the religious wackjobs and maybe we could start progressing as a species.

That's just gonna drive up inflation. Instead, invest that into better farms, industries, businesses, and schools that provide services at-cost or free. Or just use the assets left by those guys for the public good, they're already set up.

B-but billionaires have rights too!!

Seems like an arbitrary threshold. Does anybody actually need $900 million? Or $300 million? Or...

Using Hawking radiation!
