America is two-fold. The first fold being the native Americans who through societal influences are instilled in the belief that we are the best at everything, and leaders of the modern world. This creates a kind of inflated ego, and which ultimately leads to ignorance. We are a people of mass distractions. We live our lives fulfilled in these distractions. These distractions include being bombarded by advertisements and our society engineers greed and covetousness. It can't be helped. There are a few of us who have taken the time to realize this and thus educated ourselves but this is what I ultimately believe is the reason behind your concerns.
Because America is an ethnic melting pot, it needs some commonality. That commonality is the English language. The more we get away from that the more fragmented we will become.
Nothing wrong with a tossed salad. Healthy eating.
We used to be a melting pot. Where we joined each other as one as Americans. Now we are fighting to be separate again. Irish~American, Italian~American and so it goes. It is sad, I like very much to enjoy sharing a culture that is mixed and referred to only as American. We can celebrate cultural differences while keeping them under one name and not feel as though my cultural history has been lost while I enjoy your history along side mine.
For a very long time the attitude of Americans (the descendants of immigrants who arrived before the 20th century) was that being an American meant checking one's "foreign-ness" at the door. It wasn't until the mid 70s that people began embracing and hyphenating their roots. Now, arguably, many people who come to the U.S. feel no need to assimilate at all and insist upon the right to be accomodated in not doing things "the American way". There's probably a happy medium between the two extremes, but we've yet to find it.
It need a little more salt.
Yes, the mettle East brother and sister to name one.
people do not like change
A lot of it has to do with conservative isolationism. For example, there's a conservative outcry every time a state tried to change public information to make it available in Spanish and English. The motto is, "You're in America, learn English!"
One does not simply throw ingredients into a pot and expect them to mix together.
Because people really don't want to melt together, that's a liberals fantasy.
It's not everyone's dream to melt. Hell not even liberals want to melt with conservatives. They understand the folly of the melting pot.
We we're never a melting pot. We're a salad bowl no mixing but the ingredients stand next to each other.
Because most of them have their nose to the grindstone and shoulder to the wheel.
