Some of the theories that come out makes sense, but it's on a very sensitive topic so if I were to believe it then the government is covering a lot and makes me think that there's even bigger problems out there.
I say 1-1.1Tril since the ticket itself is already very costly and to receive one you should put in a lot of effort too or wait til it's in the market. People donating 100bil is generous, but you yourself have to save trillions so in that aspect, if they want one, they too need to donate just as much.
