Even if he wanted to join the American middle class (and some Indians do wish to join and have done so) the average Navajo suffers from a handicap more severe than skin color, the language barrier or insufficient education: his acquisitive instinct is poorly developed. He lacks the drive to get ahead of his fellows or to figure out ways and means of profiting from other people's labor. Coming from a tradition which honors sharing and mutual aid above private interest, the Navajo thinks it somehow immoral for one man to prosper while his neighbors go without. If a member of the tribe does break from this pattern, through luck, talent or special training, and finds a niche in the affluent society, he can also expect to find his family and clansmen camping on his patio, hunting in his kitchen, borrowing his car and occupying his bedrooms at any hour of the day or night. Among these people a liberal hospitality is taken for granted and selfishness regarded with horror. Shackled by such primitive attitudes, is it any wonder that the Navajos have not yet been able to get in step with the rest of us?
