In my humble opinion, many more people than in the lottery can win in the pyramid. The whole experience of the pyramids proves this. I can agree, (what else can I do?) That they will lose about 80%, but still it is more than in lotteries. Plus, in the rules it is clearly written that the game Ponzi is a pyramid. All is honest and there is no deceit.
Your opinion is factually wrong. Provided that the ponzi provider doesn't run away and doesn't take any fees, you're looking at a zero-sum game. All the money passes from person to person.
There are only more winners than lowers when you have one person lose a LOT.
