After all when there is an story about a sports star who is particularly gifted, you don't see other articles talking about that "they are great at basketball because they were born 7 foot tall". Or about Tiger Woods "he is great only because his father took the time to train him from a young age". Credit goes to people who take advantage of what they have. It's obvious that not everyone or close to everyone born with a distinct advantage has achieved notoriety or excelled. Sometimes that is even a negative. I often take issue with Bill Gates being born into advantage myself, but the truth is many people with the same advantage never would have ended up a billionaire so yes credit is due vs. the competition or peers you might say.
No doubt that going to Harvard has helped Gates, PG, Zuckerberg and a host of others. But the truth is most Harvard Grads don't end up where they did so yes they deserve credit and not whining from the less fortunate.
