Why do economists abstract, and is it appropriate?
Economists (and other scientists) abstract in order to be able to focus on key variables. It is appropriate, because the economy is very complex; trying to keep track of everything is extremely difficult. Thus, economists focus on relevant variables and ignore those that are less relevant to the problem at hand. Abstraction allows focus on the forest instead of the trees.
