We introduce a minimalist dynamical model of wealth 演化 and wealth sharing among N 智能體s as a platform to compare the relative merits of 利他主義 and individualism. In our model, the wealth of each 智能體 independently evolves by 擴散. For a 族群 of altruists, whenever any 智能體 reaches zero wealth (that is, the 智能體 goes bankrupt), the remaining wealth of the other N − 1 智能體s is equally shared among all. The 族群 is collectively defined to be bankrupt when its total wealth falls below a specified small threshold value. For individualists, each time an 智能體 goes bankrupt (s)he is considered to be “dead” and no wealth redistribution occurs. We determine the 演化 of wealth in these two societies. 利他主義 leads to more global median wealth at early times; eventually, however, the longest-lived individualists accumul
