In all of nature we see a constant struggle to survive. Human life is structured by the same struggle which is the basis of all values.
Competition brings out the best in people.
It provides the challenge required for people to find their true potential. Dreamers and idealists go on and on about how the world should be or could be, but they can't back it up with hard fact. Competition is the reality we have to deal with. Some people imagine that we can avoid the struggle of life altogether. They dream of an ideal world without conflict or injustice.
