I think Sullen Galda is right.
I used to share very similar views as you, Kaltros, but I joined my husband on a conference about ethnicity once and they put some new thoughts in my head that I'd never considered before.
Whites have the majority here in the US, and so all minority cultures are subject to white culture, which is displayed in anything from certain kinds of humor to foods, dress, and how we act and react in certain situations. I imagine it must be hard to be two people- one person at home, and a more white-acceptable person in public.
That being said, the white majority also has the upper hand economically. Whites sit at the top of the food chain in jobs with very little exception, and those who are minority with high-salaried jobs have probably heard, "You're more white than you are [insert applied minority here]," by colleagues and peers more times in life than they thought bearable. It's supposed to be a compliment or a joke, but what does that do to a person's confidence in his or her ethnic identity?
A minority presence in any traditionally white setting most likely means that person (or their parents or grandparents) sacrificed a bit of their identity to get there, and worked 150% more than any white person standing beside them. We may have equal rights on paper, but there
is still a glass ceiling in America for minorities. In the area I grew up, my family was one among many just didn't trust "dirty Mexicans", and when someone said, "It's a black neighborhood," they meant, "Don't go near there; gangs and drug dealers abound and you
will get shot." (Unfortunately, we hardly ever remember than an overwhelming majority of serial killers are/were white.) have negative connotations for most minorities, and the only one we have for ourselves is "white trash", which is usually a label given to poorer white people, and implies that other cultures in the same economic standing are just "trash". There is a mentality inside each culture, I think, that those within your culture are the most trustworthy. Ask yourself: If you were transferred to a new school or workplace, would you rather sit at lunch with someone from your own ethnic culture or a different one? Maybe you're not the average person, but 9/10 people would feel safer and more comfortable with someone
like them. I believe that is one reason why, after so much effort in US law systems to make all peoples equal, there are still way more white people coming out on top: White people trust other white people more, and are more willing to give like people jobs and other opportunities.
I think the college initiative to find a way to include more ethnic minorities onto campus is a good start to help break the glass ceiling. Diversity promotes a conglomerate of cultures, instead of one dominant white culture. And since there are many job initiatives starting up that are similar, maybe we will see more different-colored people in higher-paying jobs that more accurately reflects the diversity of our population as a whole.
Sorry if this was tldr for you. Didn't mean to make it that way; just wanted to flesh out my argument.
