The Hockey Stick of Human Prosperity

The Astonishing Growth of Human Prosperity

Historical Context of Human Prosperity

• The growth in prosperity over the last few centuries is considered one of humanity's greatest achievements.

• In 1000 BC, the average human faced poverty, hunger, and disease; this situation persisted through classical Greece and into the dark ages.

Life Expectancy and Quality of Life Improvements

• Before the Industrial Revolution, life expectancy was around thirty years; today in the U.S., it averages about eighty years.

• Child mortality rates have drastically improved from one in four children dying before age five to one in two hundred in developed countries.

• Modern individuals are significantly taller due to better nutrition compared to their ancestors from 250 years ago.

Living Conditions: Then vs. Now

• Historical living conditions were dire: ancestors lived in huts with dirt floors, infested with insects and rodents, while modern society enjoys basic amenities like electricity and running water.

• Even those at the lower end of the economic spectrum today have access to comforts such as toilets and refrigerators that were unimaginable for past generations.

Shift in Production Knowledge

• Prior to industrialization, people knew how to produce many items they consumed themselves (clothing, food, housing). Today’s individuals lack this knowledge for most products they use daily.

• The complexity of modern consumption involves global supply chains where a single product may originate from multiple countries (e.g., coffee beans from Guatemala brewed using Swiss equipment).

Economic Implications of Specialization

• The transition from self-sufficiency to specialization means individuals typically perform only one type of job while consuming a wide array of products produced by others' labor.

• This shift prompted inquiries into economic principles; Adam Smith's work sought to understand the causes behind emerging mass prosperity during his time (1776).

Understanding Prosperity Through Trade

• The focus has shifted from understanding what causes wealth to examining what leads to poverty.

• Upcoming discussions will explore how trade contributes significantly to our overall prosperity within an economic framework.
