Pretend your married with several childern, your in your 40s-50s, your not rich, but your not poor either, for the most part everyone around you has the same amount of money, goods, etc....
Then one day a young couple in thier 20s with kids moves in next to you, they have more, and better cars, thier kids have better clothes, food, and medical care,thier opinions carries more weight in the town...
Would you feel a little envy? Would you ask yourself why don't we have all that stuff? What did we do wrong?
Mayby i did not get it right, but are you saying that most americans got almost the same amount of money, good etc? And that europeans with anti american ideas is jealous?
