Link to originalConsider a stylized example with two countries. Country A pursues moderate productivity growth — say, 2% per year. Country B does not, at 0.5% growth. It isn’t degrowing, but it’s deprioritizing growth. In 35 years, Country A doubles its standard of living. Country B takes 138 years to do so. This rule of thumb is called the “rule of 70”: at 1% growth, it takes 70 years to double your standard of living; at 10%, just 7 years.
