Privilege has nothing to do with the proportion of successful people, though. Especially when you consider that most Asians are successful because they work harder. The importance of education is paramount in Asian culture.
When it comes to privilege, it's an innate advantage that comes with being white. You are born into it, oblivious to it, but it exists.
I do agree, however, that white privilege is too often used as an excuse for being mediocre. Yes, it sucks to not have that compared to your white counterparts, but I feel like time spent complaining is much better spent bettering yourself, putting yourself in positions of control and influence, so that you may affect change much better than your parents/ancestors.
My parents worked hard for me. They were engineers who moved here and started their own business. Most importantly, they came at an age when most people wouldn't dare dream of starting a new life in a completely foreign country and not knowing the language - they were in their 50s. Simply put, they were fearless. But they came to guarantee my future. I won't ever forget that. To say I'm motivated by their love and sacrifice for me is an understatement. Failure is not even in my sights as I work hard and smart to further myself and my future family. My parents deserve nothing less but the absolute best of my abilities and intellect. Their efforts will not be wasted.
As a med student, it's pretty much guaranteed that my children will follow the same path, or at least something similar. That's the purpose, to leave your children with better resources and opportunities than were given to you.
