Im sorry you feel that way, Americans have the abillity to monetise everything, there are lots of american rags to riches stories.
America has more infomercials selling the dream, than any other country, they also have more shopping channels, they also have more millionaires that started with nothing,and it is true that if it looks good, and sounds good, Americans will buy it.
Another American trait is you take things too personally, and they are very eager to shoot from the hip, at the slightest displeasure, which is why americans get labelled as gung ho, shoot first ask questions later, its part of what makes americans, american, and if you take it as an insult, thats your problem, as it was not intended
