What would life be without opposition?

Answer 1

If there was no opposition, there would be no need to substantiate or disprove arguments about religion, politics, and policy.

The world would be very corrupt, as the person who could lie the best would hold power both in government and private enterprises. Opposition keeps those who hold power honest.

On a scientific level, there would be less advances made in science, because collaboration criticism, and discussion breeds new ideas and theories etc.

From an artistic perspective, there would be no creativity because everyone would think similarly, dress similarly, and like the same movies books and music. Very boring indeed.
