I just had a great idea for an unbeatable Ponzi scheme. Offer a reward of infinite riches, everlasting life and an enduring relationship. Tell people that it is a free gift; all they have to do is accept it. Once they join, get people actively involved and emotionally attached. Encourage them to build relationships with other members, and to volunteer their time. Encourage them to give a portion of their income. Use their money and their efforts to grow the scheme. As necessary make use of additional tools like guilt to ensure people are participating. If people lose their sense of urgency or feel too burdened by their participation or are drifting away, give them some perspective: a little temporary pain now is nothing compared to the everlasting torment that is in store for all those who are not in the scheme.Most Ponzi schemes have fatal flaws that eventually cause them to fail. Either they are exposed as frauds or at some point their growth tapers off and outlays exceed their income and they collapse. This scheme avoids both of these failure modes: it is impossible to disprove its key claim of reward after death, and so it cannot be shown to be a fraud. In addition, this major outlay never actually has to be made to participants (until they are dead), and so it will never run out of resources. At the same time as avoiding typical failure modes, this scheme can do what Ponzi schemes do best: leverage the income and effort of current participants to bring in new participants. I imagine this scheme could last thousands of years.
