Those who think money can't buy happiness just don't know where to shop … People would be happier and healthier if they took more time off and spent it with their family and friends, yet America has long been heading in the opposite direction. People would be happier if they reduced their commuting time, even if it meant living in smaller houses, yet American trends are toward even larger houses and ever longer commutes. People would be happier and healthier if they took longer vacations even if that meant earning less, yet vacation times are shrinking in the United States, and in Europe as well. People would be happier, and in the long run and wealthier, if they bought basic functional appliances, automobiles, and wristwatches, and invested the money they saved for future consumption; yet, Americans and in particular spend almost everything they have – and sometimes more – on goods for present consumption, often paying a large premium for designer names and superfluous features.

Gossip and reputation make sure that what comes around - a person who is cruel will find that the others are cruel back to him, and a person who is kind will find others are kind in return. Gossip paired with reciprocity allow karma to work here on earth, not in the next life. As long as everyone plays tit-for-tat augmented by gratitude, vengeance, and gossip, the whole system should work beautifully.
