Why is it said that when the people are rich, the country must be rich?

When the people are rich, the country is bound to be rich. This is the real point of view.

It is the opinion of the ruling class that the people will be rich only when the country is rich.

The reason is simple because there is a ruling class.

No matter how rich the people are, it is impossible to surpass the ruling class. On the contrary, the ruling class is definitely richer than the people (ordinary people).

From a basic point of view, it is natural that the people are rich and the country is strong.

Only complete and full democracy can make the country rich and strong, but it is impossible to have full democracy.
