So the 26 richest people are worth the 3.8 billion poorest.
Basing it off forbes, the 26 richest people are worth $1.398T, or $1,398,500,000,000.
If you divided this out to the 3.8 billion poorest they would get $368 each.
I remember watching a video not long ago where bill gates was discussing how he spoke with other of the richest billionaires and sort of made a team with them to dedicate their wealth towards taking out some of the biggest killing diseases because simply giving their money away wont do the job at getting rid of poverty for the billions. I could be remembering this wrong but I believe the bill gates foundation worked on the eradication of smallpox which now it has gone saves 5 million lives a year from the disease and are working on many others but with a focus on polio.
I personally see it as poverty ridden countries having too many children and not being able to improve the community at all because of having too many births.
