All in the space

NASA decided to send a man into space without the possibility of return to the land.
 They have three candidates: an American, a German and a Jew.
 Ask a question:
 - How much money you are willing to fly?
 American responds:
 = One million dollars. I'll give it to my family?
 German responds:
 - Two million. One million I will leave the family, and the second spent on charity.
 Jew responds:
 - Three million. I leave myself a million, the second will give you a million, and the space will send American, giving him a third of a million.
