If I controlled that much money and was determined to be charitable after accounting for my own personal comfort, I'd love to perform the following experiment, give away $833 to every person in that 41.5% each month for the next 12.5 or so years. IANATL, but at $833 per month you stay just under the $10000 per person you can give each year.

The economic impact of such an act would be a huge direct stimulus to the economy and would change the lives of everyone for the better.
