Why do Americans idolize body shapes that only make up a small portion of their population?

Women- supposed to be 5'8 or taller, 120 pounds max





Men- like the warriors in the recent movie 300............minus the beards and long hair





Yet this is not a reflection of the average American from my personal experience, am I wrong?Why do Americans idolize body shapes that only make up a small portion of their population?
No you aren't wrong.


But why do people like prime rib over chuck roast?


Mercedes over KIA? A mansion over a mobile home?


It is in our nature to evaluate things, judge them and rank them bad, ok, good, better, best. Of course most people want the best things for themselves. What is hard to understand?Why do Americans idolize body shapes that only make up a small portion of their population?
I like to watch girls in bikini's while sitting on my couch drinking beer and eating pizza, im sorry what was the question again.
