In the real world it always goes the other way--the next dollar is never worth as much as the previous dollar, thus any fair bet costs more (the previous dollar) than it gains (the next dollar.)
That's why you should only engage in negative bets, aka insurance. There you are trading a next dollar (worth less) for a previous dollar (worth more).
