Which celebrity has said that a city s economic development is underdeveloped depends on the toilet

There are many similar words, and the earliest similar one I know of is what Engels said: "Historical activity is the cause of the masses." ”

Historical materialism holds that the masses of people are the creators of history. Engels once said:

Historical activities are the cause of the masses. It is the "masses in action" that determine the development of history. The masses of the people are a historical category, and qualitatively speaking, the masses of the people refer to all the people who have played a role in promoting the development of social history, and quantitatively speaking, they refer to the overwhelming majority of the social population.

In different historical periods, the masses of the people have different contents, including different classes, strata and groups. The most stable main part of the masses of the people has always been the working masses and their intellectuals engaged in the production of material materials. In the course of historical development, the masses of the people play a decisive role.

Therefore, the masses of the people are the creators of the material wealth of society, the creators of the spiritual wealth of society, and the decisive force for social change.
