There are near 800 billionaires in the USA. Assuming all only have $1 billion dollars and it is all invested, applying the "4% rule" gives a sustainable $40 million each per year. With $10 million to personally spend, that gives $24 billion a year for charity and public works.

I failed to find a list of the costs to solve various issues. Homelessness could be solved in a couple years.

The numbers provided are just a starting place. Many problems are extremely expensive. Actually working to solve them would help.

Contradiction in terms

We don't have the supply to fill the demands to simply throw all billionaires money into solving every crisis. That is why wealth inequality is so vast. Dollars are a made up system. In its raw form it's just paper. Backed by the govt. Where as it used to be backed by the gold standard which is why we hoard so much gold. That is a real tangible asset.

Paper is just paper its artifical, it's only good once spent. You can have infinite money if they forever printed it. Instead we balance inflation and deflation and finite supply that is dwindling the more we clear cut and strip the earth.

I can't even imagine what color the sky would be in that world...
