You are taking Obama, the first ever black president and a highly privileged stand-out to claim that it's already normality. Well, it's not. Stand-outs are not the standard. Just because, to make up an example, 1 of 20 black people get accepted into an ivy league university and the other 19 are white, does not mean you can point to that one black dude or girl and say "see, there you have that person you claim they get denied stuff".
I am white in Germany, so i am as natural in this country as it can possibly get, so i can't tell you how my skin color keeps me down. But i can tell you that i witnessed numerous examples of different treatment of people in the same situations where the only difference visible was their skin color, yet they have been treated differently.
I can give you one example: In the post office there was couple weeks ago a customer who was not able to speak german, he was white. So the post office clerk talked to him in english and explained stuff to him, took his time etc. All good. Couple days later i was back at that post office waiting for my turn. There was a black guy wanting to send a parcel and had difficulties with the forms as they were in german. He asked for help and that exact same clerk looked at him top to bottom before answering (black dude looked absolutely fine whatsoever, not drunk, not homeless etc) and said in loud german the explanation. The black dude obvsly did not get it and asked again in english. The clerk repeated the same stuff again in german and looked annoyed. So, there you have your everyday example.
Another example would be how me eating at a restaurant witnessed the waiter bringing me the food and telling me to enjoy my meal and if there is something else i'd like, i shall call for him. Next to me was a darker skin man, i assume from india, he ordered in perfect german. When the waiter brought him his food, he just put it down on the table and turned around. No nice words whatsoever like with me.
"white privilege" does not necessarily always mean that you get denied a job if you are black while the white guy gets it. it can be also found in smaller things. but those can add up and many small things in your everyday life adding up, they create your everyday reality. and this reality is somewhat different for a darker skin person here, that i can tell you.
now you can say: yeah well, germans are nazis. some are, i am sure of that. but so are some americans, some brits, some australians, some russians. it's all about what ethnic group is in the majority in a certain country or area.
