The difference between a moderately prosperous society in 2000 and a moderately prosperous society in 2021

The moderately prosperous society in 2000 was still a low-level, incomplete, and very unbalanced development. A moderately prosperous society in 2021 will be a higher level of moderate prosperity, with a more developed economy, a more complete democracy, more progress in science and education, a more prosperous culture, a more harmonious society, and a more prosperous life for the people. Well-off refers to the economic status of a family that can maintain a moderate standard of living, and also refers to the socio-economic status of a moderately developed country.
