Trick question. Even though the expectation value of the right-hand button is 50 times that of the left hand, half the time you get nothing. But with the right hand button -- almost everyone would see a large, immediate leap in their lifestyle. So while it's trying to act like the marshmallow experiment, it's not. The guaranteed payoff is much larger than a marshmallow. The deferred choice doesn't always pay off. The correct answer is "both". (Kobayashi Maru, break the rules. 😉)
