-pay everyone making minimum wage or below 100$ for registering to vote. Cost about 170m.
-devote some portion of it to animal safety and care taking. Even stuff like sanctuaries for feral cats, dogs, and other non-adopted creatures as opposed to euthanasia.
-public libraries that provide services people otherwise wouldn’t have. Like a public square almost. Have a clearing house match up community interests with speakers and the like. Ie inviting religious people or leaders from religions foreign to the community to come in and discuss their beliefs and culture. I also want people to be able to request and invite things like lectures from theoretical physicists. Also do stuff like letting people request time on musical equipment in the building to learn how to play - or even just see if it’s for them.
Granted, all of this would probably negatively affect that biweekly 1 billion!
