From Charles Karelis. This is a good thumbnail summary of my book. One tweak and one extrapolation. The audio hovers between saying that the benefits of a small improvement (hammering out one dent, paying one bill) are nil until an improvement threshhold is reached and saying that the benefits are small when the problems are big but gradually grow as the improvements accumulate. My book argues that for the poor above the threshhold of sheer survival, the benefits of small increases in income are small, not nil, but grow gradually greater as income rises. The proof of this in a nutshell is that even poor people are not indifferent to small income increases, as they would be if this were a threshhold situation. The extrapolation: the reluctance of the very poor to exert themselves for small objective improvements, explained in my book, extends to exertions other than work in the usual sense, including exercises of willpower to reduce obesity
