> It is more fruitful to highlight the disadvantages that a group of people experience so that we may fix them and bring everyone up.
I see it as the same. It's one thing to say, "I don't have to worry about X because I am white" and basically the same to say, "They do have to worry about X because they are non-white".
> If these advantages were as powerful and prevalent as you suggest, there wouldn't be more millions of white people in poverty.
I don't think anyone who believes in white privilege believes that it is a monolithic escalator to success. It makes some things easier. But there also exists privilege due to class, health, access to education, gender, climate, family support, etc.
There are many, many types of privilege, and being white is just one of them that has an interaction with the others. (e.g. is it more advantageous to be white and able bodied or white and not able bodied? Is it more advantageous to be white and poor or black and poor? etc.)
> It's used to attribute individual excellence to generalized advantages of a certain group of people.
If you believe that individual excellence is the only factor, then how would you explain the demographic data about fortune 500 CEOs? One hypothesis is that privilege played a role -- that they had advantages due to race, class, gender, health, etc. that combined with their individual achievement resulted in their success. If privilege didn't play a role in their success, is it just a coincidence that the demographics overwhelmingly skew white male?
