Fear as Motivator

I believe fear, as the most effective and popular motivator, is a good motivator. Only under fear do humans evolve. Only under fear do humans work. Only under fear do humans prosper. Without fear of failing, students wouldn't be studying. Without fear of babies, people would make crazy monkey dances all over the world endlessly. Without fear of the lack of money, nobody would work. The society human lives in is based solely on fear. Many films, particularly Disney, who ruined just about every Pixar movie with nice morals, tried to state fear is a bad thing. "Fear is for cowards. Control over fear is not the best way. Fear is characteristics for evil people. "....However, fear is the absolute basis for we humankinds. Without fear, none of our society structure would function properly. Basically, as long as we are living, fear is an integrated part of our life. This is not about good or bad, brave or coward, smart or stupid. This simply part of our existence as human beings.
