I always use Syria for it to explain: First "IDEALISM"

In the year 2011 most, if not all people where supporting the rebels of Syria ... as our "ideals" demand that we support those rebels... and "Assad is Bad" .. we supported these rebels because our "ideals" demand us to! But now 10 years later the War has not ended and the "Idealism" framing of this War "Assad Bad" has not ended either ... For a Idealist - 10 YEARS OF WAR - is not a factor , the only factor that matters is "Assad Bad" .

Now if 10 years of War is not a factor for you , we can assume that 20 Years of War would not be factor for you either.
So in Praxis the "Idealist" is actually demanding eternal War ... and he demands his eternal War why ? On the Base of his "Ideals" of course (idealism is a cruel Joke)

MATERIALISM is what you do, the Moment that 10 YEARS of WAR constitute an actuall significant Factor in your Analysis.

HOMEWORK :

explore the MATERIAL Value of a standart US- Individual and contrast it with his IDEALISM Value ("how he is imagining himself") ...
