The soldier is just that. They fight in actual wars. They risk their lives to protect the "morals" of their "country". None-the-less, they want a better future for their children.

When the war is done, the soldiers children are the farmers. The farmers rebuild, and want. They want material objects. Maybe it's the food they lacked when they were young. Maybe it's a gas guzzling sports car. None-the-less, they want a better future for their children.

When material "wealth" has been achieved the artist is born to the farmer. The artist has the time to take actual pleasure in life's little wonders. But they also have the time to see all the injustices in the world. Injustices, vial enough to start a . . . war.  None-the-less, they want a better future for their children.
