Some say that having 100 million yuan now means you can live a life of leisure. Those who had 10,000 yuan back then probably thought the same way. Many people probably kept their money in the bank. What can 10,000 yuan do now? Moreover, back then, a person with 10,000 yuan had a status and position no less than today's billionaires. In the 1970s and 80s, there were only about 10,000 people with 10,000 yuan, but their actual purchasing power was more than 100 million yuan today. By around 2000, the value of being a 10,000-yuan household had significantly diminished. At that time, winning a lottery for "5 million" was popular. After 2015, large apartments started to cost hundreds of millions. So you need to understand that living a life of leisure is just a slow death. Deflation only happens occasionally for a few years. In the long run, within 20-30 years, wealth will be inflated to near zero. I met some 80-year-olds in Hong Kong who were still working. They had millions or even tens of millions in savings. When asked why they were still working so hard, they said they retired in their 60s, traveled the world, and stopped working. They bought two apartments, renting out one to support themselves. In recent years, they found that prices had risen and the rent wasn't enough to cover their expenses. They worried that in a few years, before they died, their money would be gone, so they went back to work (my professor, Shui Shuo, is one such example).
