Both urban and rural incomes have risen steadily, and people's health and life expectancy have improved. In the market economy system, material resources are extremely rich, people can play their own initiative, to obtain the greatest material enjoyment. The steady increase in the total retail sales of consumer goods in urban and rural areas shows that people's living standards are improving, which is an ignorant guarantee for people's happiness.

This is not because having money makes people unhappy, but because not having money makes material abundance a growth point of happiness that disappears.
