Would you like to be a millionaire?

Millionaire billionaire multi billionaire. I'd put the money to work. Medical research, inventing. I'm curious about accounts like retirement accounts that could be created to pay out to low income workers to fund things like insurance co payments, dental work and the like. Similar programs could upkeep rural roads. I'm also interested in fighting gentrification in the form of building codes and HOAs. Starting programs to educate people about property rights and exposing these scams.
