Why did the Soviet Union flaunt democracy and the United States declare freedom during the Cold War?

Because the Soviet Union was a socialist country during the Cold War, and socialism was a system in which the people were masters of their own affairs, then the implementation of democracy meant that the Soviet people were masters of their own affairs, and China was also democratic.

America is capitalist, aiming at making money. Freedom means that everyone can do what he wants, live or have material things.

This is also closely related to the development of the two countries. America has always been capitalist. After one or two hundred years of development, the people are relatively rich. The step of being the master of the country has been realized, and the next thing to pursue is freedom.

The Soviet Union just experienced the baptism of World War II, and everything is recovering. After the end of fascist rule, the people were masters of their own affairs, and the national conditions of the two countries were different.

But because of the cold war, the two superpowers are showing off their homes, both to prove to the world that they are better.
