a fool and his money will soon be parted.
i dont think this is good, but its the reality we both live in.

ok another example:

i go to a market and tell all people: anyone can come here and get a ticket. every ticket has a 10% winning chance.

^ its the same. except that with the ponzi model you know that the first ticket always wins and the odds getting more bad over time.

a honest ponzi is really just a game and no theft.

if any lottery or casino does not state the odds and advertises like any ticket wins the police will come to them - as they come to ponzi owers who told their customer that anyone will win.
