Being an individual is a big thing! A closed mouth doesn’t get fed. This means if you don’t speak and make yourself known you won’t be noticed or given opportunities. So, it’s all about standing out from the crowd.
Our language shows this. I don’t know any language were “I” is capitalized in a middle of a sentence. People who don’t follow trends or are trendsetters (especially) tend to be praised. A lot of people think they’re unique even if they’re not just because they put their own spin to a trend that a lot of people but not the majority are doing. So you’ll see people doing their own thing or not tending to care what other’s think of them. Or that’s what it looks from the outside.
Standing from the crowd is a big thing here. That’s why many people try to be trendsetters but it doesn’t always work out that way. Not only that but people are always creating new things or improving what’s already been created because capitalism ($$$) is a great incentive for people to think.
As well as we can be pretty selfish overall. Especially, against other countries. It seems that they are more willing to share or maybe that’s from the outside. This of course is my opinion of the U.S in general.
Overall, I would say we are a pretty individualistic country. So being yourself isn’t so bad here.
