Brazil is actually a pretty rich country. It's just that the wealth is exceptionally highly concentrated at the top. Brazil has enormous resources and potential, but all that potential gets sucked up by the big boys in their club. Although I know what you mean, it's important to distinguish Brazil from a genuinely poor-all-over country where there is not much wealth anywhere. Even in poor or average neighbourhoods in the big cities, you can see a person with nothing and then another person drive by in a BMW.
No, because Batman isn't a real person with real constraints.
Sure, I mean, if you have a $1B, then you get to have a lab with gadget people making cool shit and you can buy a fighter jet and a personal submarine and you have the detective agency too.
But you don't get the rogues gallery of super villains. You don't get new knees every week. You don't get to save your local city, because the problems are mostly the problems that the people cause themselves. And solving all those problems makes you a tyrant, not a hero. And even then, the problems are the same we've had since before history.
This is why in the real world, we have philanthropy mostly aimed at education and the alleviation of extreme poverty and diseases as the main outlets for the billionaires. Because it's the only thing we think that works at all.
I guess, if you really wanted to be Batman, you could fund yet another study that would state how best to give away dollars. But, without even having to look, I know that there are a few dozen of them out there already and they all pretty much say the same thing: that it's muddy and hard to discern, but maybe if you squint, education and making sure people have food and shelter.
To be Batman, you already can do it. It's mosquito nets for the poor, it's giving that bum a $100 and an hour, it's volunteering with prisoners to get them to read, it's making sure your kids' classmates have a snack before the test, etc.
So yeah, the real world Batman is a boring stressed-out Mom that's active in the PTA, her church/community-center, and local politics. Real World Bruce Wayne is Steve Rogers before the serum.
I find GiveWells approach the most satisfying when I ask myself “how can I make my charity go the furthest”. https://www.givewell.org/ I also highly recommend Famine, Affluence, and Morality by Peter Singer, it’s a perspective changing book. Also, great comment!
In my last job, the service mesh was responsible to do retries. It was a startup and the system was changing every day.
After a while, we suspect that some services were not reliable enough and retries were hiding this fact. Turning off retries exposed that in fact, quality went down.
In the end, we put retries in just some services.
I never tested neither retry budget nor deadline propagation. I will suggest this in the future.
You are right about convenience, but here, 1% fee makes a huge difference to make both ends meet.
You can give alms with pix, to show how widespread pix is.
