When I was at Osaka University, my professor told me the reason why economists use unreal models as an explanation of reality.
He quoted from a great British economist of the 20th century,
A model which took account of all the variegation of reality would be of no more use than a map at the scale of one to one. Joan Robinson (1962)
Since then, I've tried to study the tools of dynamic optimization.
variegation: –noun
1. an act of variegating.
2. the state or condition of being variegated; varied coloration.

Me too, but we can see something interesting and valuable in the process of building models, and that's why we try hard to build it...
