If trillions or close to one trillion - heavy investments, heavy usage, adaption and implementation of the plans to end hunger globally that were proposed to Muskrat by UN, development of similar plans to end homelessness, addiction. Immediate global warming countermeasures. Influence political agendas of countries towards implementing socially beneficial policies like UBI, robotization of manual labor. Basically taking off the burden off of working class and humans as a whole.
