Should people continue to be traditionally thrifty and frugal as their standard of living improves? Why?

The traditional thrift and diligence should be maintained. The lessons of history tell us that even if the country is developed enough and our life is really rich, the virtue of thrift and diligence should not be lost. Therefore, in times of hardship, we have to use diligence and thrift to tide over difficulties, and in times of affluence, it is even more important to cultivate our character with habits of diligence and thrift. If we can abide by the code of hard work and thrift in this period, it will have unlimited benefits for our future growth and development; on the contrary, if we pursue luxury from childhood, it will not only be unfavorable to the country and the family, but also bring adverse effects to the development of the individual.

As the saying goes, "You are born in sorrow and die in peace".
