As consumption declines, the middle class slips back into poverty, while people at the bottom can no longer afford to spend. How should we respond to this downturn in consumption? This book takes an in-depth look at the development trends of the next 20 years, interpreting the mindsets of rich and poor, career awareness, future technology, population, the cognitive dividend, understanding society and getting along with others, logical communication, time management, self-discipline, side hustles, freelancing, and information asymmetry.
