Funnel $10B in housing to Los Angeles and you'll build less than 100 units of housing, because the inflationary push of that money would balloon the cost of per unit housing. I don't want to imagine the effect of that on middle class housing.
Funnel $10B of food to xyz famine region and you've undercut local farmers for generations. Happens all the time [1]. And that's assuming you can get the aid past local corruption.
These problems aren't as simple as people assume, and I'm low-key happy young naive Billionaire's are avoiding these issues instead of trying to throw their weight around.
FWIW: Sam's already funneled a bunch of money into green energy production[2].
