The Unheavenly City – Edward C.Banfield The Nature and The Future of Our Urban Crisis
At the lowest socioeconomic level, lower-lower class, the time perspective was often only a few hours, or minutes, such as in the case of the hopeless alcoholic or drug addict, who thinks only about the next drink or dose.
At the highest level, those who were second- or third-generation wealthy, their time perspective was many years, decades, even generations into the future. It turns out that successful people are intensely future oriented. They think about the future most of the time.
The very act of thinking long term sharpens your perspective and dramatically improves the quality of your short-term decision making.(From Meraki)
